Dont waste your time locking method sucks - RISE Armament RA-905 AR-15 M-LOK Handguard

13.5 handguard on a sharp bros hellbreaker lower and spikes tactical billet upper . Ve built plenty of high end ar15s well over $3800 this was goin to go on my newest build $4800 total build once done . ONLY REASON I ORDERED THIS HANDGUARD was because the fluting on the handguard where the barrel nut is matched thr fluting in my upper receiver n thats it . I got itntoday went to install it . Barrel nut was on tight no problem went to install the handguard the anti rotation tabs were not snug and i can see why they pit anti rotation tabs on this handguard because the locking mechanism sucks . You can not get the screws in tight enough to make this thing snug and tight to where it doesnt still move side to side . I tried to tighten them screws so tight it even stripped 2 out of the 3 screws and still not tight enough to hold in place without shaking . I never write reviews but i shoulda listened to the other reviews . STAY AWAY DO NOT WASTE YOUR TIME BUYING IT THINKING YOUR GUNA BE THE LUCKY GUY THAT HAS NO PROBLEMS . Because that was me ignored the reviews n thought maybe they fixed the issues …. NOPE not at all . Will be returning handguard today
