Awesome rifle!


I've had this rifle for a couple years and I've put thousands of rounds through it without a single malfunction. I spray the BCG with some Rem oil or CLP before shooting (just like we did in the Army) and give it a quick wipe down with an old t-shirt and bore snake every 3-4 range trips. I got mine during the 4th of July sale and used the cash I saved to add an MOE stock, vertical grip, sling, and QD attachment points, BCM Gunfighter grip, Stream-light, a Bushnell red dot, and a VG6 Gamma 556 muzzle brake and this thing shoots like a dream. I think I've spent a little over $600 all together. I shot a buddy's Daniel Defense ($1500 for the base rifle) recently and I like mine better. :)

Great Rifle - clean BCG first

by -

Great rifle. Was my first AR. Bought Black Friday. Running great. Only suggestion, before firing, disassemble, remove BCG, disassemble BCG, clean thoroughly, oil liberally/thoroughly, then reassemble. Radical owners manual didn't give this info. Runs all ammo very well (after I did the above steps). Been firing mostly cheap steel. Trigger is above average for plain Jane mil spec trigger. Better then a trigger on my son's last AR. Handguard Is very nice, received compliments on it. Today was hitting 8" steel plate at 100 yards with open Magpul mbus sights. Loving this so far.

Good but problems with hand guard

by -

Bought one for my brother for Christmas. The rifle seems good and he’s happy with it. The problem is the hand guard game lose and fell of during firing. Then the screws rounded out after trying to tighten it back up.
