Looking for any information on suppressors for the M-14/M1A. I recently read that the Marine Corps is using one of the Ops Inc. cans on their DMR rifles; I have seen an advertisement that SWR has one for sale, their ad states that Ops Inc. does not sell to the public. AWC also builds a can for the M-14. I have had an opportunity to shoot an M1A bush rifle with the AWC can; really quiet but seems to have a lot of blowback, even with a modified gas screw. Does anybody else have any experience suppressing their rifle, or for that matter a desire to?
