Left my $.02 on Jek's post on the Faxon industry page about the Ti slim FH, and a lighter carbine length 14.5 pencil. Speak up and let's get behind this, find it here:

Sorry dude, the aluminum a2 from dark hour defense is gone and it doesn't look like it's going to return. The titanium cam pins are around, I'm pretty sure every other person on this thread has a spare or 2. if you don't have one by Friday email me. Ahrion idk what you had going on with the taccom buffer, it sounds like too much gas but you're experienced enough at this that I can't believe that's the problem. Did you try jp or spikes gas rings? Most broken bolts are caused by gas rings going bad. I use a dsa aluminum carrier with a rca adjustable key turned almost all the way down, I've used 2 different brands of titanium cam pins, a mystic black bolt with JP gas rings, 300 blackout subsonic Nemo spring, taccom buffer, and it's on a faxon mid length pencil 16" barrel. How many rounds until the bolts were ruined? Do you think the ion bond coating could be causing issues with the gas rings?

Couple questions for the crew.
Have any of you milled the deflector and dust cover lugs off a magnesium upper? How about the FA? I’m getting ready to try this and looking for any and all tips. Also, I went back and read through all the pages I missed and someone (breaststroker?) mentioned re profiling a Faxon barrel? I went back and couldn’t find it again, but thought I had read that. On the Taccom buffer, what diameter are you guys drilling them to? TIA |

The 16 inch Faxon pencil barrel 556 originally came in at 19.04 ounces. In their infinite wisdom they enlarged the gas block support area so idiots could put 2 inch long gas blocks on the barrel. So all the later barrels start out at 19.4 ounces.
So I sent the 19.4 inch spare barrel to John Thomas @ http://www.retroarmsworks.com/ and he cut it down a lot while still being safe. Getting a CF charging handle and a lighter weight CF buffer tube/stock (less than 1.69 oz.) Hoping for 2.33 pounds, more like praying! |

Cutting weight in the CH area ain't easy, the design is pretty lightweight as it is. To really cut weight there, making the rifle a reciprocating side charger with an CF handle would probably be best, but usually uppers with the big slot cut in them for such charging systems are over built / heavy to compensate, so that's a non-starter.
Is anyone actually working on a traditional style CF CH? |

Got the following reply from Faxon by email when I inquired about the Ti slim FH:
Thank you for taking the time to contact us! Unfortunately, no, there are not currently any plans to produce the slim flash hiders in titanium, but we do appreciate the suggestion and will take it into consideration. Thanks, Martin Customer Service Faxon Firearms Anyone have the skills and machines to make something similar or revive the aluminum A2 if they don't decide to take a shot at it? |

The lightest charging handle you can do right now is a triangle charging handle with a sintercore xrs kit. Might be hard to find the kits now.

Just FYI for the herd, I spoke with Jonathon from Incognito Arms earlier. He's going to be down for a while working a job out of state, maybe as much as 6 months. He said he would post a notice on his website when he's out and back in. He said his lightest stock is now lighter than what's currently in the PWD. Hopefully I'll be able to verify when he's back in production.

I can tell you right now there is NO WAY the Oregon Rifleworks Lightweight Barrel @ 16 inches is the claimed 15.4 ounces.
From their photos the threads on the barrel are standard 0.50 inches for 556/223. So their gas block is larger @ 0.625 inches. So their barrel weighs about 21 ounces or more, unless they can PROVE it on a digital scale and have a weight next to it for calibration. |

Al has the highest k. Therefore at allows for heat to transfer from the barrel nut to your hands better than Mg or CF. That's why Al us used in heat sinks and pots and pans.

Could be that the mg alloy is like half the mass of Aluminum, plus it's not exactly magnesium, it's alloyed with aluminum. If you want to dismiss the experiences of both of us though then that's your choice. I mean what's going to get hotter faster, 4 oz of mg/Al alloy or 7 oz of aluminum? Plus the aluminum will cool down quicker between firing cycles.
