The M76 handguard features the wedgelock barrel nut attachment system which is one of the most durable on the market. It also features 45° M-LOK slots at the front for more light and accessory mounting options. The upper receiver is made from 7075-T6 aluminum Cerra forgings and type III class 2 hardcoat anodized black. The upper receiver comes with the forward assist and dust cover assembled as well as an SOLGW BCG and Radian Raptor ambidextrous charging handle. The inside of the receiver has a dry film lube applied to decrease friction with the bolt carrier for smooth function.
The lower receiver is decked out with aftermarket furniture like the B5 Systems carbine stock and Magpul MOE pistol grip for better ergonomics than standard Mil-Spec equipment.

Ratings & Reviews
Limited edition rifle nearly identical to the12.7" M4-76, I own one of those too. This one came with a Surefire War Comp and a very thin shim on the 13.7" barrel to make 16" vs the SOLGW NOX and 12.7" barrel.
<br> Rifle shoots very softly with the A5 buffer system. It's gassed properly which is refreshing in a mostly overgassed industry. Runs like a scalded dog when shooting 5.56*. Rifle length is great for maneuvering around obstacles and transitioning in and out of vehicles. Absolutely love the trigger in this thing. Very clean break and nice reset.
<br> *If you plan to shoot .223 and or steel case plinking ammo plan on getting an A5H0 buffer with this one as the weak .223 didn't cycle the Rifle. I tried a variety of .223 and none of the brands would work. The buffer weight change and a peer check by the SOLGW customer service got me back straight.
<br> You cannot go wrong with a SOLGW product.
They’re out of stock everywhere for a reason
SOLGW is absolutely top notch in every sense of the word. If you’re familiar with them, I’m sure you’re already following them on IG. There’s details on this rifle you just don’t realize you’re getting until you’ve shot more “budget friendly” options. Down to even taking the slop out of the safety selector. I’ve put a few hundred rounds downrange so far with zero issues. If you’re torn between this and the 13.7, they’re identical other than muzzle device. This has the Surefire Warcomp which is slightly shorter than SOLGW Nox, hence the .2” difference in barrel length to get it to the 16”. You will not be disappointed with the rifle or the SOLGW family.
