Re: How to remove sling loop from Bushmaster gas block?
You'll have to drill the rivet head off and then use a Brass punch and a good solid blow with a hammer and you can drive the body of the rivet out. Really not too difficult at all, a 1/8" drill bit will pop the head off, make sure the rifle is secured and take it nice and easy. You may want to use a center punch, this will keep the bit from walking out on you.
If it's the rattling around that bothers you, you can also tape it up or use some tool handle dip to keep it from clanking around.
