Our Honor Guard is looking for restrictors to go on the end of the M1A(M14) rifle so we can fire blanks when we do Military Honors for our Veterans. Without the barrel restrictors, the action will not cycle due to the reduced pressure from the blank round. The actions then have to be cycled by hand. I have been looking around and cannot find anyone that has these available. Does anyone have a contact that might have a solution to this problem? Thanks for your Help and God bless all our Veterans!
