I'd appreciate some feedback on a potential re-construct of my rifle as pictured below. I've used a 10.3" based around a Colt barrel as my primary AR for several years now. Generally speaking I like it a lot and do not have reliability issues, even when running suppressed. What I'm wondering about is moving to an 11.5" barrel. An inch isn't that much (that's what she said), but the numbers say it's quite a bit when it comes to velocity. I use 62gr Speer Gold Dot, which is less reliant on velocity for terminal performance, but it's still only about a 150yd gun. My idea of a mini-recce is really a do-all gun. There's not enough distance in my local terrain to warrant a true long range gun, but the 200yd out to maybe a 400yd max envelope is realistic.
If I could just go buy an 11.5" Colt HRT barrel for anything like $300, I'd probably just do it and be done. Unfortunately the ones I can find are $500-$700. I do have a new-in-box factory Colt 10.3 as a backup/replacement to my current barrel along with a bolt. If I were to go 11.5, ultimately I would want two. Finally, from an optics perspective, I have always had an Aimpoint on my 10.3 and when I had a magnified gun (LPVO or ACOG) it was on an upper built around a 14.5" SOCOM barrel. One thing I really liked about those barrels was their accuracy. Here's a 10-shot 100yd group out of one of those 14.5 SOCOM barrels using a 3.5X TA11 ACOG:  By contrast, this 10.3 Colt (gov profile) with same ammo is almost 2MOA:  So my hope is that with an 11.5" HRT barrel, which is heavy profile, I could get more velocity = better terminal performance, plus the added accuracy benefit. Short of forking out $500-$700 for a barrel, anyone have any other thoughts to get the performance, or just stick with the 10.3 for what it is (reliable, short, reasonably accurate)? Current setup:

Quote HistoryOriginally Posted By HAMBURGERATTACK: Question for Mini Reecers using Atlas Bipods... I am wanting to start using a Atlas PSR on my 11.5 SBR/LPVO with Mlok rail. How many slots of pic rail do I need for good attachment of the atlas adm mount? Is a 3 slot enough? Or do I need 4/5? As stated above, 3 slot will work just fine. 5 is better.. 4 is hard to find. I don't have an ADM mount, I've got a LaRue. Same basic premise... |

@Bullseye_Doc_Holiday
That's a sweet looking rig brother. As for your Q.. for me, I'd be happy with it as is. Trying to shoot STUPID tight groups @ 100yrds? Yeah, maybe look into a barrel swap. Realistic expectations for what it is now? I'd be happy with it. 5 shot groups @ 100 might yield a tighter MOA. Or different ammo, etc. If you're dead set on chasing the rabbit, take a look at Wilson Combat's 11.3 match barrel. It's not expensive at all. I've yet to really test mine out but from the little time I had behind it last summer I was happy with it @ 50. Time will tell, hope it works out. Again, super nice build as it sits! |

Current setup: https://i.imgur.com/OfNLcw9.jpg I would look into a SS barrel. A CL barrel will not be as fast. It can still be as accurate but the speed will be slower than a SS barrel. As stated above get the WC 11.3 barrel and you will be getting max velocity in that short barrel. Give it about 100 rounds before you see your true velocity. I used to routinely take my 11.3 WC out to 500yd Edit: your NX8 and an 11.3 WC barrel is MR perfection. Find a medium RAS and with your AAC can you would have a serious MR! |

Current setup: https://i.imgur.com/OfNLcw9.jpg Dude! I literally put a gun together yesterday that almost looks identical to yours!! Except I used a surplus M68 as my optic until I can find an Aimpoint T2 to put on it. I also have two 11.5s and do notice a discernable difference in accuracy and velocity compared to one of my other 10.3 barrels. I have a SS steel 11.5 with a 223 Wylde chamber and a Roscoe 11.5. Believe it or not, the cheaper Roscoe holds a tighter group at 100 meters compared to the SS barrel. I'm not sure of the manufacturer of the SS 11.5, but I did purchase it from DSG Arms back in 2017 and it is a good barrel. But, that Wilson 11.3 barrel seems to be a really good shooter as well from all of the pics of the groups being made with it in this forum. My buddy had a Colt 14.5 SOCOM barrel cut down to 11.5 and it's super accurate, but it is really gassy. Premature parts wear is now an issue on his setup. |

I changed the optic mount from a couple posts up to an ADM 1.93 from the Badger 1.70. I run most of my other LPVOs in 1.93s, so the 1.70 just didn't feel right. I have a Badger 1.93 c1 mount on the way if I change my mind from the QD, but for this rifle I wanted QD, since I built this to be my new SHTF rifle. Also put a set of Ultradyne BUIS on there. They really do seem like another level of BUIS as far as intuitive use... I should be able to get out next week to get some rounds downrange with this, but I am happy that it is set up better.
As an aside, right after I took this picture this morning, I slipped on some ice and fell on my ass. LOL

Well I did it. Colt 11.5 Heavy's came back in stock at ThatWhichShallNotBeNamed, so I jumped in for Tree Fiddy. Also gave Mr. Bill some more of my money and got a 10.5" MK4 to go with it. When did that come out? I somehow missed that as I thought they only had the 9.5 and 10" Fed rails (other than the 13" and whatever). Overall, I gained 1.2in and 8.4oz. I believe it's a worthwhile trade off for increased long-term durability and (hopefully) accuracy.

Picked up a second Razor and mounted that today.
 Next step is to get an RMR and Reptilla mount, and I have another upper and lower set inbound to start another project with. That one will probably be a Triarc 13.9” barrel and not sure what else yet. |

I want to say 2016-2017 is when we started seeing Colt (kinda ) consistently mark their lowers with QRs/DMs. That same time period some distributors started selling off SDN Mexico rifles. I'd imagine that run of lowers/rifles started to get marked with the updated inventory QRs/DMs. (I've also seen some SDN lowers without the QR/DM codes) |

Does anybody have a KAC Medium RAS with a standard (non-KAC) midlength barrel that would be willing to take a picture of where the gas block is located in relation to the end of the rail? I'm wondering if I can get away with using one of the new Allegheny Arms tapered gas blocks with a Medium RAS and mid length barrel and still have it be a closet to flush fit with an AEM5.

The 13.07 is the length to use for the spikes and the 13.56" is the length for the Allegheny with a midlength. I started this project a few years ago with a couple other guys in this forum. Just got my AEM3 approved and my barrel is on its way back from D. Wilson as we speak. I think it came out to something like 12.75" to work with the AEM3. Here’s some pics with the spikes tapered block to give you an idea. As mentioned, I had to shave a cunt hair off my ff ras for the can to fit.  Attached File Attached File Attached FileD.

I got the 6 MOA dot just to pick it up faster. Anything even close to 100 I’ll get on the glass. I need to recheck zero on the scope though to see if taking off a set of rings changed anything. |

Quote HistoryOriginally Posted By Bullseye_Doc_Holiday: I'd appreciate some feedback on a potential re-construct of my rifle as pictured below. I've used a 10.3" based around a Colt barrel as my primary AR for several years now. Generally speaking I like it a lot and do not have reliability issues, even when running suppressed. What I'm wondering about is moving to an 11.5" barrel. An inch isn't that much (that's what she said), but the numbers say it's quite a bit when it comes to velocity. I use 62gr Speer Gold Dot, which is less reliant on velocity for terminal performance, but it's still only about a 150yd gun. My idea of a mini-recce is really a do-all gun. There's not enough distance in my local terrain to warrant a true long range gun, but the 200yd out to maybe a 400yd max envelope is realistic. If I could just go buy an 11.5" Colt HRT barrel for anything like $300, I'd probably just do it and be done. Unfortunately the ones I can find are $500-$700. I do have a new-in-box factory Colt 10.3 as a backup/replacement to my current barrel along with a bolt. If I were to go 11.5, ultimately I would want two. Finally, from an optics perspective, I have always had an Aimpoint on my 10.3 and when I had a magnified gun (LPVO or ACOG) it was on an upper built around a 14.5" SOCOM barrel. One thing I really liked about those barrels was their accuracy. Here's a 10-shot 100yd group out of one of those 14.5 SOCOM barrels using a 3.5X TA11 ACOG: https://i.imgur.com/oc7RMcR.png By contrast, this 10.3 Colt (gov profile) with same ammo is almost 2MOA: https://i.imgur.com/BAruc7A.jpg So my hope is that with an 11.5" HRT barrel, which is heavy profile, I could get more velocity = better terminal performance, plus the added accuracy benefit. Short of forking out $500-$700 for a barrel, anyone have any other thoughts to get the performance, or just stick with the 10.3 for what it is (reliable, short, reasonably accurate)? Current setup: https://i.imgur.com/OfNLcw9.jpg This setup is sick. How do you like the NX8? I'm attracted to the overall size and weight with the capability it provides. Wondering if the gripes i hear about it arent as bas as people say. |

Yeah the eyebox is no Razor 1-6x but it is a damn good optic. |

Wondering if the gripes i hear about it arent as bas as people say. The above post is good. I love the setup overall (though I have replaced the barrel with an 11.5 HRT and I like it better.) I view it like a Glock 19. I can shoot a full size Glock more comfortably, but targets and shot timers say I can shoot a G19 just as well as a full size. It just tells on me quicker if I let things slip. The trade off is worthwhile for the more compact size = easier to conceal. It’s just less forgiving. The NX8 is the same. Compact and capable, but less forgiving than something bigger and heavier if you let your fundamentals slip. |

 I blame this thread for this build. Upper: VLTOR MUR Black River Tactical CHF Optimum 14.5" Dead Air FH pinned and welded by John Thomas at Retro Arms Works CMT DRT 13.0 handguard Radian Raptor SL charging handle AO Precision BCG Lower: Aero M4E1 Aero standard carbine buffer tube B5 Sopmod Bravo A2 grip master race Schmid Tool 2 stage trigger via DSG Arms Optic/Light: Razor Gen II HD-E 1-6 Badger C1 1.7" Modlite PLHv2 in a Unity Fusion mount Modlite Modbutton Lite Still need to tie down the cable for the Modbutton but waiting to play with it at the range first. The short section of Picatinny rail on the front of the handguard is for a Harris Bipod mounted to an ADM QD mount. |

Took the 14.5 Wilson barreled gun to the range today to re-zero with a 1.93 ADM mount.
