Does anybody have any FIRST HAND experience with McFarland Gas Rings?
Here is a link:
M-15 McFARLAND GAS RING
We have had now 4 separate gas ring failures among 7 rifles in the last year. The original rings were crap, and the replacements (Although purchased from Bushmaster) also failed. I am hopeful that these will correct the issue.
Any comments welcome...
