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.

Parts:

Lower: Matrix 7075-t6 Forging
Upper: Aero Precision
Barrel: Faxon 14.5 Match Series Mid Length Gunner 223 Wylde 416-R
Bolt Carrier Assembly: Faxon 556 FA
Brake: Faxon 3 Port .620", pinned and welded
Gas Block: Faxon .625 Lightweight
Gas Tube: Brownells Melonite
Hand guard: Foxtrot 15"
Grip: Magpul MOE+
Safety Lever: 60 Degree throw (friends castaway)
Trigger: Trigger Tech Adjustable (2 Stage short reset, sub 3lbs total)
Mag Release: Ambi Arms Unlimited
Sights: DPMS Rear A2, Hi Viz front sight post
Rail: 6061-T6 Type II Anodize, Sight Radius 20.5" (DIY)
Trigger Guard: 6061-T6 type II Anodize (DIY)
Stock: BCM Gunfighter
Buffer: Carbine US made, CAR Buffer
Grip Accessory: Strike Industries Link
End Plate: Radiant Arms Titanium 7075-T6 QD

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

Mother of God.....

What type of groups do you get without a scope? How much does that magnum carry handle add to practical accuracy?

Making wind and elevation corrections

1st 4 shot group without corrections. Closer to 1.75-2 MOA. I was squinting quite a bit and using a large sand bag FYI.

Practical accuracy, maybe 2-3 MOA without squinting and a bag. The Hi-Viz post is a bit on the wide side for paper.

I'll have to go to the range to get more photos. Pictures are proof.

What is that thing supposed to be on the top of your gun? Looks like the aqueduct in Seattle. Can I stack two scopes on top of each other for rapid engagement?

So, you basically have a rifle sight radius on a carbine? That’s pretty neat. Sort of like the dissapator concept taken to the next level with a free-floated barrel.

It kinda looks like you're trying to make an AR into a G36. While I'm not ready to mont anything like that on my AR's, I still commend your skill with a CNC and at least having a vision for something and see it materialize by your own hands. I don't want to sit here and bash it, it's not my place to do that and whether or not it really improves capability or function, you at least envisioned something and you made it with your own two hands. (and CNC Machine). That's America boss.

Now about that trigger guard - you should make more of those trigger guards. I like the design and it looks very well finished. Good job on that.
