It's a barrel nut. Nothing more, nothing less!


It's a basic barrel nut. Does what a basic barrel nut should do. It seems of good quality. There's not much more to say about it.

finish is a little rough, needed a different barrel nut for my app

i needed a proprietary barrel nut exactly like this 1 except in reverse where the indentations are against the receiver so the threads begin in the opposing side. live and learn! pay attention to what you are working with. otherwise, this piece will work just fine for your everyday mil-spec GI style setup & handguard.

part I needed and good price

Excellent and prompted service by Primary Arms

LBE AR-15 Barrel nut worked perfectly for me. Just make sure to grease the threads, torqued to 30 ft-lbs and back loose 3-4 times or until it stops advancing (to seat the phosphate coated threads). The teeth slot was almost lined up to the gas tube in mine so all I have to do was adding a little more torque until the next slot line up with the gas tube and the torque was slightly over 30 ft-lbs.

Primary Arms customers service was amazing.
Thank you.

Great Company

Barrel nut fit and finish was as expected. My review is more for Primary Arms. 90% of my AR build was purchased here and I am so impressed. Secure transactions and reliable delivery. Tried doing business elsewhere and came back to Primary. Outstanding service.

AR-15 Milspec Barrel Nut

Received AR-15 Milspec barrel nut very quickly after ordering. Barrel nut appears to be top quality and fit perfectly as I expected.

It works and is solid.

The threads were cut nicely and had no issue getting to the proper torque specs.

Worked. Not much to say about it.

Good nut

It holds my barrel firmly in place, my Adams Arms piston fit’s perfectly in between the peaks of the barrel nut and my Samson EVO hand guard holds tight to it. It’s a good nut!
