16″ 5.56 NATO AR-15 Rifle Kit — 12″ Window M-LOK Handguard
The handguard on this build is a 12″ free-float M-LOK rail with lightening cuts machined into the top and sides, shedding extra ounces while venting heat away from the barrel during rapid strings of fire. It’s finished with a mil-spec six-position stock and mil-spec pistol grip, a simple and proven setup that leaves plenty of room for your own optics or accessories down the road.
The upper ships fully built: 16″ barrel chambered in 5.56 NATO, 1:7 twist, carbine length gas system, and the M-LOK handguard already torqued to spec. Drop it onto a compatible lower and you’re ready to run.

Q: Does this kit include a lower receiver?
No — you’ll need to provide your own stripped, complete, or 80% lower receiver. Everything above the lower is included and assembled.
Q: What handguard comes installed?
A 12″ free-float M-LOK rail with window lightening cuts machined into the top and sides, already mounted and torqued on the upper.
Q: What stock and grip are included?
A mil-spec 6-position adjustable stock with buffer tube kit and a mil-spec pistol grip.
Q: What caliber and twist rate does this use?
5.56 NATO with a 1:7 twist rate on a 16″ chrome moly nitride barrel. The 5.56 NATO chamber also accepts .223 Rem ammunition.
Q: Is the upper pre-assembled?
Yes — the barrel, gas system, BCG, charging handle, and handguard are all installed. Drop it onto a compatible lower receiver and it’s ready to run.
Q: What length gas system is this?
Carbine length, which is standard for a 16″ barrel build.
Q: Are sights included?
No, sights are sold separately. The flat-top upper accepts any Picatinny-mount optic or iron sight.
Q: Will this fit my lower receiver?
Yes — this is a standard mil-spec AR-15 upper and fits any compatible mil-spec stripped, complete, or finished 80% lower receiver.
Q: Does the handguard free-float the barrel?
Yes. The 12″ window M-LOK handguard is a free-float design — it attaches to the upper receiver, not the barrel nut, so the barrel isn’t under any contact pressure from the handguard.
