I want to mount a sling adapter to my M4LE, but the locking ring on the buffer tube was staked
at the factory. I have the lower in a mag well vice block, but I can't seem to budge the locking ring
with a wrench. I considered tapping the wrench with a hammer, but I'm afraid it will put too much
presure on the mag well and screw it up. So, what do I do?
Thanks
