Radical Firearms Gen 3 M-LOK Handguard Primary Arms Exclusive - 15"

I am more then impressed with this free float rail. I don't have experience with Radical Firearms parts until now. It fits the barrel nut like a glove and was easy to install. No more timing the barrel nut for the gas tube. Mine has no sharp edges and is well made. My M Look accessories fit like a glove. What impressed me the most was when I bought mine I got it on sale. This rail is light weight and solid. Being a Texan, it is made in Texas and PA being a Texas company makes it four thumbs up. It looks awesome on my Rifle.

Total waste of time. The hand guard would not fit the barrel nut provided properly. You could not put enough tension on the bolts across the split to actually grip the nut and the forward bolt that assists in locking the guard to the nut did very little to help anything. Even with enough stress to nearly strip the bolt heads it had enough play in the guard to make contact with a gas block with marginal finger pressure. Even a cheaper Aim Sports hand guard holds far better than this. Don't think I can even return it at this point. Wish I had gotten a chance to try it sooner.

I had a round handguard on a older AR. I wanted the rail and M-Lock to attach a set of pop up sights and this worked really well for me. It went on easy and seems to be holding up after a few range trips.

7 month update - I’m still as happy with this rail as the day I installed it on my rifle, it has a little road rash which is to be expected since I don’t baby my firearms. When I installed it I used blue lock tight and all is still well with that. Since installing this budget friendly free floating I am able to shoot 1/2” grouping with Sierra match king from a bench. Outstanding craftsmanship, fit and finish. Still happy with it.

Overall it's a good rail for AR rifle build the color is a little bit off but overall it's a very strong rail and it does look good on the rifle in the end. Best to have a gunsmith install it for best results.

Got this in sale. Very nice quality for the price.
The rounded contours make it much more comfortable to hold than most other rails. Mounting nut and screws look plenty sturdy. I would buy it again.

Shipped fast. Arrived within 4 days of ordering. Awesome handguard. Extremely light and easy install. Liked the first one so much, had to order more the day it arrived. Highly recommend this handguard.

Could use 1-4 Qd mounts.. lol other than that just a good quality product well-built simple assembly also

Fit great and is a really well built handguard.

This handguard is the one for you. Just install the barrel nut according to instructions. No shims to mess with. Self aligning. Be sure not to forget that anti seize compound. A little goes a long way!!! You can't miss with this purchase.
