The Underworld Arms Aug CQC Handguard is 5.5" long and is machined from T6-6061 with a black anodized finish and includes a top rail for extending the iron sight radius. The rails can be removed to expose M-lok slots. The handguard includes a black oxide 304 SS locking nut, a black oxide 304 SS mounting nut, and a black polymer centering plug for use during install.
When installed the quick change barrel feature is functional and gas adjustment is accessible, the original grip can be left on or removed.
The UA Aug Handguard mounts to the barrels bayonete threads using our proprietary hybrid method that takes inspiration from an AR15 style barrel nut and the Aug's locking flash hider nut. Be sure your barrel has these threads, 300blk barrels and some European civilian Augs do not.
This 5.5" Aug handguard is designed for standard 16" barrels, if you have a 20in barrel you will need to wait for our longer handguard to be released.
This handguard will fit on A1, A2 and A3M1 receivers, it is not compatible with SA or A3M2 receivers due to their extended top rail.
Installation:
To install the handguard remove your muzzle device, degrease your bayonet lug threads and the mounting nuts to remove all oils, apply rocksett or a similar threadlocker to your bayonet lug threads. Thread on the square locking nut with the unthreaded ID facing the receiver, thread on the wing shaped mounting nut with the wing side facing the receiver. Orient the flats of the mounting nut at the 12 o-clock and 6 o-clock and tighten the nuts together. Slide your handguard on and attach it to the mounting nut with the included 8-32 screws. Be sure to use your choice of thread locker on the screws so they do not back out. Test the barrel's quick detach function, if the handguard rail engages the receiver then unthread your mounting nut a half rotation.
Rocksett has a 24 hour setup time, you do not need to rush the process there is plenty of time to line everything up perfectly.

Customer Reviews
Good customer service really quick shipping no complaints buy with confidence the owner is a cool guy !
I’m new to cloning/building so I didn’t realize the mounting screws were in the mounting nut (my fault just wanted to mention in case someone had the same issue) OVERALL love the handguard Aug is looking tuff and in my opinion much more comfortable to hold (and you can run that tacticool light /pressure pad combo. Install is not bad if you follow the instructions and I Highly recommend.
I had high expectations for this piece and they were not subverted. Not only it gives the rifle a meaner, more menacing look but, it makes it more customizable. I've added a peq 15 and a flashlight. It looks fantastic. The only counterpoint here is the forward imbalance due to the extra weight but, easily compensated if you keep the vertical grip on front.
