These rifles have ended up a bit differently than originally intended, especially after I found the AR15 makes a better ultralight rifle. Here's how they are equipped right now (have yet to paint the hideous, shiny carbon stock).
Up top is the .223 with a 16" featherweight CarbonSix barrel, 2nd FP NX8 4-32x, stock bottom "metal", Silencerco Omega 36M with Griffin Armament taper mount. 7lb 13.6 oz.
Below, sits the 6mm ARC with a 18" sendero CarbonSix barrel, 2nd FP NX8 4-32x, DIP bottom metal, Griffin Armament Bushwhacker 46 with Griffin Armament taper mount. 8lb 2 oz.
I intended to use the NX8 temporarily on the .223, and then move it over to the ARC when the new barrel arrived. I enjoyed the scope so much, that despite its weight I got another.
For anyone curious, I get 2650 fps with Hornady Match 108gr ELD-M ammo out of the ARC. Shooting through a bunch of that factory ammo to get myself some brass for reloading.
Both barrels were prefits, headspaced without issue, and live up to the 1/2 MOA CarbonSix guarantee. Thanks
@CarbonSix !
I had Oregunsmithing bottom metal on both of these rifles, but in the end could not get them to feed reliably. The Grendel bottom metal tended to bind or completely miss picking up a round, and the .223 bottom metal liked to eject multiple rounds out of the magazine while cycling the bolt. I also tried out the new MDT Howa Mini bottom metal and magazines, and immediately returned them. The MDT bottom metal design seemed promising, but in the end felt like corners were cut to either save costs or rush the design to production. I can explain further if anyone needs to be talked out of spending money on that product.
Upcoming Changes:
- Add DIP bottom metal to the .223
- Possibly move my GA Optimus Micro to the 223, and temporarily shuffle the Omega 36M to the ARC to drop some weight from each (both shoot so well that I'm hesitant to change anything
- Once I get my ATF permission slip, replace the Bushwhacker with an AB Raptor 10 on the ARC
- Paint that damn carbon stock (something ASAT-like)
