Griffin Armament produced a video outlining the benefits of their SPR suppressor. The SPR is a new 5.56 over the barrel suppressor (reflex) suppressor being offered as a high performance, high value can. They compare it directly with its Ops Inc competitor and the SPR seems to stand up well to the comparison.
I have been very impressed with the value that Griffin Armament is able to offer with their compensators and flash suppressors. It looks like they are able to bring that same level value to their suppressor line.
Check out the SPR at Griffin Armament.
