This handguard is crafted from 6063-T6 aluminum and is hardcoat anodized a deep black. The durable rail offers a slim, modular profile.

I got this on a bit of a whim because it was on sale for $399 I'm very impressed I had a trigger job done on it,the factory trigger was pretty bad but with new trigger I shot a little over 1" group at a 100 yards with generic 55gr I have only put about 150 rounds through it but 0 feed or jamb issues

The price was great. The quality and fitment is great. I had to go on line to Radical for an owners manual. Overall I'm very pleased.

Bought it on sale... this rifle is really good for the price point

Well put together rifle


I caught it at the $399 price. Was looking for a range and truck gun. I have two more really nice builds so I did t want to spend too much.
<br>This rifle fit the bill. I installed a Blaze NB polished trigger and a flat wound buffer spring. Slapped a PA 1-6 LPVO sfp on hit and had it zeroed in 12 shots.
<br>Feels solid, little wiggle so for what you get for the price is unbelievable. Nitride BCG, Mlok rail.
<br>The only cons are the trigger and safety selector.
<br>Just a standard mil-spec trigger, easily replaced and then there’s the ambi safety selector. It’s too long on the right side. It rides against my index finger making it difficult to engage. And it isn’t tactile so it will go past the fire position.
<br>I will be replacing it with a standard selector soon.
<br>You don’t have to do any of these thing and you will still have a decent rifle. It will still probably outshoot most of us.

Can’t beat it

Was looking for a new AR15 when this deal rolled around and could not pass it up . Has everything I was looking for and price was a steal.
