Attached to Anderson lower with Radical pistol buffer kit. Fired 600 rounds of both steel and brass. No problems. Able to keep rounds within 6" at 100 yards if I did my part with a microdot and a rest. Just jagged holes at regular pistol ranges of 15 yards and under. IT IS SICK! Like the smooth forend. No idea why it was priced less than the comparable Radical 10.5" upper.

Attached this upper to a Spike's Crusader lower registered as a pistol build. Perfect fit and color match! 1.5" groups at 50yds shooting from the hip with a LaserMax attached, with my 55gr reloads. Not bad for a pistol......My prayers are with the flooded Texan's.
delta ring design concern.
Remove the Handguard and check the Torque Specs of the Delta Ring. The spaces between the holes are so far apart that you either torque loose or very tight that you may not ge to the next hole.
Fast shipping. Nice uppers.
Shipped fast. 1st time out it fired fine for 1 mag. 2nd mag it wouldn't eject. Couldn't figure it out at the range. Just ended up "single shooting it" by pulling the charging handle back for every round. Got home, took it apart and cleaned it. Noticed there was a mark on the barrel by the gas block about 1/16" from the receiver side of the gas block. Pulled the bcg out and pushed on the gas tube. It moved. Ended up taking the handguard off and moving the block back. Set screws were loose. Took them out one at a time, locktite on them and put them back. Never had another issue again.
<br>Just wish Radical Firearms would STOP using those stupid star screws on the handguards. Too fragile and strip out easy.
<br>Just a recommendation before using it, make sure everything is tight. Use threadlocker (NOT RED) on the gas block set screws.
Nice Buy for the money
Great price all around very happy with the buy. Fit and feel is good and the 10.5 is showing really good groups at 25 yards.
My second one!

Just received this for a pistol build and it is flawless. Great quality in perfect condition. I bought the same one in 16 inch for another build and performed perfectly as well. I really like the simple handguard. It is comfortable, and clean looking. You wont be disappointed.
