tomb_lin 0 Posted July 12, 2006 Report Share Posted July 12, 2006 I removed the front and rear sight to mount a scope low. when the rear sight blade is removed there is an opening with the gas piston visible... Any blowback issues from this ? anyone fit a block of some sort? Pictures and instruction are appreciated Scott Quote Link to post Share on other sites
O.S.O.K. 0 Posted July 12, 2006 Report Share Posted July 12, 2006 No, there are no issues - the rear sight leaf does nothing to avert gas. Quote Link to post Share on other sites
