Poor fit and finish

by -

I'm not a fan of this handguard. This is the worst fitting one I've used yet.
The actual guard itself decent but the barrel nut it comes with is awful. It's very generic, there's no notch for the gas tube alignment, I had to reconfigure the shims 800 times to get it timed and the fitment between the hand guard and the upper receiver is not very tight. Also, it attaches to the barrel nut with 6 screws and they're big and clunky, not color matched to the guard, and the whole thing ends up looking like something from Ikea. I bought this a few months ago so I had a 15" FDE guard on-hand for my next build and now that I'm there, I'm really sad I can't return it.

Easy to Install.. Wont work for a vertical grip - No M-lok holes

by -

The pictures dont show this well but the M-lok holes are towards the barrel and not in a place for any sort of a vertical drip

I like it

I was trying to build a fde ar15 and since the brand I usually get was out of stock everywhere I settle on this it’s not 100% together yet waiting on mid length gas tube you will need a box wrench for youto put on to torc it. The screws line up at 65 lbs for me to secure hand guard. It has a fairly nice finish on it and that’s about it for my review

Nice Hand Guard

by -

This is a very nice low profile Hand Guard great look and great price

Great rail for the price


The rail is VERY light but still sturdy. Great fitment. It seems like every rail i buy from them the quality gets better and better. The indexing is a pain but that is with any rail that uses indexing. My next one will be the clamp style.

Great hand guard

Looks great, fits great, easy to install. My only gripe is I wish the m lock slots extended a little further back on the bottom. The FDE matched aero precision upper/lower nicely, which is always a concern going with different companies.
