I purchased an early AR100 about 6 months ago, looked great, almost new.
I've owned one previously, love the rifles since I first saw it when I served in Korea in the 80's.

When attempting to remove the bolt carrier group and gas piston, I can't get the charging knob to go all the way back for field stripping. I have to tap it firmly to the rear with a rubber mallet to remove the bolt carrier group. When I place the piston and bolt carrier in the rifle independently, the both move freely.

Any ideas?? Never had this problem on my previous Woo...


Edit: Found the problem. Screws for scope mount were too long causing binding on gas piston assy.
