Anyone know if the Smoke Composites or Wilson Combat Smoke Composites stocks are identical or are there some dumbing down or cheapening for the Wilson. I am chasing price and between the Smoke website and Optics Planet (with coupon), for the Wilson, there is price difference. Just trying to determine if the is an actual difference.
Thanks |

Finished a part I had been working on for awhile and replacing that dropped another .25 ounces off the total weight. Then I worked on a few other things I had been brainstorming on to get another .07 ounces off bringing the weight from 2.36 to 2.340 lbs. Getting almost impossible at this point to make it any lighter but 2.338 is realistic and I would like to make it to 2 1/3 lb eventually. The total weight with optic and mount is now at 2.48 lbs. I am going to work on the mount and finding titanium hardware for that. You can't aim without an optic. |

That 2.9 pound Grendel is a pistol, not a rifle like Jason's and mine with full 16 inch barrels. His barrel is just over 11 inches.
That guy obviously doesn't visit this thread, otherwise he could have cut a couple of ounces more. And look a lot less ugly and would look a whole lot cooler. I don't get the Grendel caliber, shorten the barrel that much and the velocity will drop way too much. The bullets drop at 300 yards will exceed the ability of that scope, what he's going to have to hold 3 feet over the target? |

16 inches is a good barrel length for grendel, gives you like 10% more power than 7.62x39 and far superior ballistics.

So what.....he didn't build it to compete with you, he built it to use....That guy obviously doesn't visit this thread, otherwise he could have cut a couple of ounces more. And look a lot less ugly and would look a whole lot cooler. Cool is in the eye of the beholder....I kinda dig the whole Rat Rod look. I don't get the Grendel caliber, shorten the barrel that much and the velocity will drop way too much. The bullets drop at 300 yards will exceed the ability of that scope, what he's going to have to hold 3 feet over the target? Why would you think that? The 6.5mm Grendel performs fine out of shorter barrels, 10.5 inches was a common barrel length offered by the cartridge's designer. I developed the 12.5 inch barrel length for it which is now an industry standard. You can shoot steel plates at 500 yards with his pistol and ethically hunt medium size game out to 300 yards. His optic of choice is a 3x24mm ACOG for reaching past red dot distances. Seems to work well. My only suggestion was if I had built it I would have threaded the muzzle and fitted a titanium brake. But, he's going to use it as a light weight backpacking and hunting gun and didn't want the brake. He has his own style...I can dig it just like I can appreciate your build. They are very different, but both are cool in their own way. Did you see how light Jason's rifle is?? WOW, very cool!! Let me ask you this, what do your 5 shot 100 yard groups look like and how far have you shot your 5.56mm rifle? |

I kinda like 18 inches for hunting and 12.5 inches as a general purpose length. A lot depends upon what your individual needs are. But I thought it was interesting to see someone build an ultra light Grendel. I also like the way he went about doing it, old school hot rodding style modifying here tweaking there... |

Gunwritr, you don't happen to know David Fortier?
I just don't see anything special about this build, many things aren't accurate. Guns & Ammo Book of the AR-15 material, not to me. The New Frontier trigger group weighs a lot less than 2 ounces. There are several buffer tubes for pistols now that weigh less than 2 ounces. I don't like Rat Rods or Rat Rod pistols. I think I would prefer an article about Jason's 2.33 pound AR15. Or my 3.85 pound 308 AR with a legal 16.1 inch barrel. Jason could take that barrel and come up about 2.2 pounds. JP Rifles’ Ultra Low Mass Operating System (LMOS) bolt carrier (5.7 ounces with a bolt) is the lightest option around. Just saying Faubion’s pistol could have been a lot lighter. |

Well then you are in the right place! I just read your full article, I really enjoyed it. I got good news for you, there are several manufacturers making magnesium handguards still. V7 weapons systems and their sister company dark hour defense make them. JL billet makes one now too, called the nano. It may be the lightest currently available. Only way to get lighter is an original bcm kmr with a stitchclimber/black label holster barrel nut and v7 titanium mounting hardware.

This thread is the best Ultra lite thread anywhere. Using unmodified parts you can now easily build an AR pistol under 2.9 pounds, a little harder is an under 3 pound AR in rifle length.
Three or four years ago the MagPul K grip was the lightest at 2 ounces. Then for some reason they increased to weight to 2.2 ounces. I drilled a lot of holes into a K grip, best I got down to was 1.5 ounces. Then the Hogue 15 degree grip came out @ 1.5 ounces stock, we immediately cut it shorter and some got down to 1.1 ounces. Then the titanium 3D printed grip came out late last year, mine came in at 0.7495 ounces. For the longest time the Smoke Composites CF stock was the lightest at 2.4 ounces and another 0.1 ounce for the aluminum castle nut. Again late last year the Incognito Arms CF stock came out at 1.8 ounces (in the shortest length) and all versions were lighter than the Smoke. I did a little trimming on the butt stock pad and it now weighs 1.69 ounces. I am getting another one that will actually be lighter than 1.25 ounces! A MUCH better idea for an AR15 article would be to take advice from this forum and build an under 2.9 pound AR15 rifle using parts unmodified. Not everyone wants to drill and scrape receivers etc. But there would be a lot of gun owner interest in a AR15 they could assemble that weighs LESS than a Ruger 10/22 takedown Even in 223/556 it is many times more powerful than a 22LR. Faxon barrels are usually the lightest unmodified barrels, they have many calibers, lengths and profiles. If you start with a larger caliber like the amazing (lie) 300 BO the larger bore diameter with the same exterior profile means a lighter barrel. This thread has a wonderful data base with real verified weights. Many times manufacturers LIE about their weights. It is now also possible to build an AR308/6.5Creedmoor under 5.5 pounds using unmodified parts. Getting it down below 4 pounds like mine is a LOT of work, yet no parts were ground down or highly modified. There is a HUGE amount of gun owners who would love to build a large frame AR10 under 6 pounds. Since the first lite weight parts came out 3.5 years ago, most AR308 parts makers are sold out most of the time. When AR magazines announce AR308s just under 7 pounds, I laugh a lot. I could easily build a AR6.5 Creedmoor with 20 inch barrel about 5.0 pounds. Tell me the gun people wouldn't like that. |

Five pounds is heavy for me, my lightest AR308 with 16 inch barrel weighs 3.89 pounds!
Actually I have a VERY BAD shooting shoulder. When I first started building AR15s, I did all the stupid recommended things like heavy carrier and heavy buffer. Only thing that actually worked was the butt stock from Israel that allowed even 4'8" women to shoot the AR. Once I discovered adjustable gas blocks, adjustable carrier keys and good muzzle brakes, everything is golden. My 3.9 pound AR308 actually shoots softer than my 6 pound AR 6.8SPC. The aluminum 308 carrier (JP Enterprise) actually weighs less than a standard AR15 carrier. I say a standard AR308 action is like a 10 pound sledge hammer, my action (BCG+buffer) is more like a ball peen hammer. I made a mistake once last year. Note I said once. I had put a new carrier key and adjustable carrier key in my AR308. But I forgot to close off the adjustable screw, it was WIDE open. Darn near tore off my arm. Closed down the screw to closed then slowly opened up so it would stay open after last round from magazine fired. Then shot another 80 rounds with zero shoulder problems. On bad days I have to cover the shoulder with lidocaine, and every night I take 2 Naproxen so I can sleep. Some days I can't raise my arm up even with my shoulder. Those days I don't bother to shoot LOL I have been shooting ultra light AR308s longer than anyone else, to survive I had to learn all the tricks of recoil. I had one of the very first titanium 308 carriers, Toolcraft wouldn't sell it to me until they knew I knew how to build AR308's. Quizzed me for 2 hours. But there is nothing like an under 5 pound AR308 or my new flame, my 5.5 pound AR 6.5 Creedmoor. That Creedmoor can do almost anything. Yotes with the 95 grain SMKs to the 147 ELD X hunting round for deer and hogs, and even 180 grain ammo. |

There is indeed a lot of great info here, it is a valuable resource. Downside is, due to the length some info is harder to find as time goes by and parts evolve and the thread has become so long. But agree with live in very interesting times where we can build incredible light pieces for a variety of tasks... |

One area which I have tried for two years now to get industry to address is an ultra lightweight optic. One company was very interested in the concept, thought they could build a scope in the 4 ounce range but......nothing after people got moved around....I'm going to try again a couple weeks. Have the perfect opportunity coming up. I think that is the missing piece to the puzzle......I think there is a much bigger market out there than companies realize..... |

The lite weight optics are only a dream right now. You are pretty much stuck with a one inch tube and smaller objective lens. Leupold has been the leader although I have a 4-10 power that weighs 10 ounces. I use higher power scopes (18 to 24 power) a lot to site in my rifles and check accuracy. But for hunting even my old eyes can use a lower 10 power scope.
With lighter alloys the variable power scopes say 4 to 10 power could be as light as 8 ounces. A 42 or 44 objective would be a huge improvement over the 40's. Scope optics have come a long ways in the last 5-6 years, I had to chuckle when Nikon came out with their new 3-9 P series scope that had almost 3% better light transmission than their older M series scopes. When I contacted them they said that was true, then stopped quoting the P series light transmission! The leader in scope mounts is Aero Precision, but they are impossible to get hold of. Their 1 inch scope mounts for AR's are about 3.1 ounces. If they would change out the steel to titanium the 8 screws would cut over a 0.15 ounce less. I took one of their extended versions and cut the rail attachment down over an inch and cut one steel screw, weigh is 2.75 ounces, would be about 2.5 ounces with titanium screws. Scope mount is still rock solid. Maybe you could discuss this with them. There is a market out there for lighter scope mounts. Lets face it, most Red dot type sights suck for real accuracy, a 2 MOA Red dot is rare, I want better accuracy than 2 MOA. If they could actually build a useful scope at 4 to 6 ounces there would be a lot of sales. It's not just light weigh ARs now, there are a lot of under 6 pound bolt rifles out there now compared to 5 years ago. |

Yes sir, that is the lightest carrier available! Very nice quality product for a great price. Be sure and get some jp precision ground one piece gas rings or spikes ion bonded gas rings to keep the carrier bore in good shape. And it goes without saying I think that adjustable gas is required. I usually use the rca adjustable gas key for max weight savings. As far as bare bones light as you can get optics the shield sms takes the cake right now. The thing is barely there and you can even get a polymer mount. They offer the 1 moa dot but it's not quite bright enough in my opinion. The 4 is better for outdoors.

Only other roll pin I can think of is the port door but it's pretty much impossible to extract as far as I know.

Hmmm, you have a point, there's not many universally required roll pin that everyone would use. Not every upper needs a FA, and some of us aren't even using a bolt catch. Trigger guard is built in to plenty of lowers, so no pin there. Gas tube roll pin and charging handle are pretty much the only ones, and I'm guessing some CHs use different pins.

Recently saw a company that is using a screw into a gas block. One side takes a roll pin, other side takes the screw. I could go for that in titanium as well as the 2A bolt catch screw.
I am cutting the 3/4 inch titanium button head grip screw down to 1/2 inch. Can't use an aluminum hex head grip screw with the titanium 3D printed, they work great with the Hoge grips. Would like to see 8 or 16 of the titanium screws for the Aero Precision mounts, the steal screws weigh 0.28 ounces, so about 0.15 ounces in Ti. The 308 cam pin is big and heavy, a titanium one would be great, maybe coat it with one of those slick coatings. Made slightly larger than the "Mil spec" 308 cam pins they would not have as much slop and last longer. Now titanium gas tubes would make a nice weight savings, much more than the little roll pins. Why not? |

All I have left is the BCG and the handguard to purchase and I'm still waiting on the 2A Palouse set to come in from being back ordered. Once I put it all together I'll be looking to the gram counter experts here to help me get under 4lbs.

If someone could convince one of the manufacturers of lightweight parts to offer a titanium carrier key that could save some weight.
It’s a non stressed part and would be perfect in this application. |

That's an excellent point...no reason the key couldn't be Ti, and it's actually a pretty good sized piece of steel in an era where we are shaving fractions of grams.

Faxon is the place to go for verified lite weight barrels. 7.5 ", Gunner, 300 BLK, Pistol-Length, 4150, QPQ •Barrel Twist: 1:8 weight 0.87 pounds or 13.92 ounces.
Every CMMG barrel I have weighs more than listed. Loony, I never stake the key, I do make sure the bottom of the gas key is perfectly flat (most are not) and then use blue or red Loctite. Never had a malfunction, never! |

A couple of years ago I ran across a company in Las Vegas who were going to make EVERYTHING in titanium. All the screws, even the buffer spring. Trigger everything including the spring. So far nothing from them. A pipe dream, but I would still jump for some of the parts.
But maybe you guys can wake them up. Try https://www.applied-neutronics.com/shop |

Changing some stuff around. I will be listing my 2A Arms Ti RBC on the EE very soon. Figured I'd give this group a shot before the dirty, unwashed masses. If you're interested in it, PM/email me.

Anyone ever seen sales on V Seven handguards? Their 10 inch handguard is my last part but wow, that thing is expensive! It's a purchase for next month most likely.

Look at dark hour defense (vsevens sister company) for a more affordable lightweight handguard. Bauer precision has good prices on them.

Quote HistoryOriginally Posted By pscot468: I can confirm v7 has the occasional holiday sale and sometimes free shipping. I'm liking the JL billet hyper light handguard better right now though. I just wish it came in a shorter length than 13.5 in. Strong side tactical sells v7 stuff at a discount too.

Was just about to ask in GD if lightweight builds were still a thing.
Figured I would check this thread out to see if it was archived. Still alive and well.  I guess my last AR build will be a lightweight one after all.

The ultra light crowd might be niche, but it's among the most dedicated. This thread will never die.

I need to decide on a lower receiver(s), handguard and another thing or two..... probably going to build a 10.5 inch pistol and a 16 inch carbine. Might just do an SBR instead of a pistol. Still scratching my head on a few things. I will probably build a couple guns and evolve them over time. I need to go through my parts, find a couple barrels and send them out to get spun down.... |
