Avoid at all costs
by Ixodes -
Avoid this poorly made piece of crap at all costs. I have SBRs and was looking for a 10+ inch upper in 300 BLK. I keep telling myself “you get what you pay for” but I never learn. Spend the money on BCM, DD, Aero, or ANYONE else.
<br>The dust cover was bent, the finish was poor, but I could have forgiven that. The holes for the takedown pins were so poorly centered that they were off by a measurable 2mm. Impossible to secure any of my multiple AR lowers. I will never buy a product from Radical again.
