SilencerShop has a lot of info on Silencers. very informative. Apparently, some silencer can be switch out to different rounds by changing the baffles, but it reduces the effectiveness. You'd have to research a lot more, but Silencer Shop has a lot of info on their website.There are a few in theory that can be used on different .30 caliber rifles. (SCAR 17 and AK) You just need to find the suppressor mount from the manufacturer that will have the correct thread pitch for each rifle you have listed. That may be tough. For the PS90 I do not think you can have an effective .30 cal suppressor on smaller diameter bore. That and finding one with the correct mount/thread pitch.
become FFL SOT with demo letter = where all the big toys areNo. Civvies in the US cannot have Machine Guns made after 1986.
You have to get a FFL and SOT, plus a 'Love Letter' from a gov agency to get your hands on one. Then you can only posses it as the entity that holds the FFL/SOT, and once that dissolves you can no longer hold the MG.
Agreed, I only mounted my trijicon 5-20x50 on the scar once and immediately got a leupold 3-9 VX-R patrol. Now the scar has magnification while staying light and nimbleThat, is a lotta glass for the 17 carbine. Might I suggest glass with a smaller objective diameter?
I would suggest the ADM Recon-S mount. Pick it up with the Tactical Lever option. The levers are a bit larger and thus easier to manipulate. You should be able to keep your rear sight as well. It also looks like you have the scope to far forward.
