Total Weight: 6.8 lbs as shown complete, no mag empty chamber
Sight Module: 17 oz fully assembled, 20.5" Sight Radius, A2/A4 Compatible
So far the rifle shoots great. With a 1-4X Bushnell AR Optic .75 MOA using Frontier 62 BTHP (5 shot), iron sights 1.25-1.5 MOA benched using 55 PMC Bronz (4 shot).
The concept of the rail was to help point shoot quickly and align the sights as you gain a check weld, plus I just wanted to make it. It's built to use A2/A4 sight modules to allow for easy ranging. Durability, Time will tell with round count and slamming it on barricades.

Faxon Barrels and Bolt Carrier Assemblies have been very impressive. assembled and tested 2 uppers both 223 wylde match series. 14.5 and 16 mid length using a CAR buffer and standard springs, Aero uppers. Barrels are a snug fit and bedded with lock tight and torqued to 40-45 ftlbs clamping the barrel not the receiver. This has yielded sub MOA groups with quality ammunition. The barrels do need 200-300 rounds for break in and favor mid weight bullets, haven't tried heavier than 62gr.
Tested with a Leopold VXR Patrol 3-10X, 5 shot groups
Hornady Spire 55gr ~.75 MOA (within the 150-200 rounds in)
Hornady Frontier 62gr BTHP ~.75 MOA (250-300 rounds in)
PMC Bronze 55gr ~1-1.25 MOA
