The Spike's Tactical CAR-9 Fake Can gives you the looks of having a 10.5" suppressed rifle but doesn't come with all of the expense and paperwork that's required for the real thing. This is how it works; The CAR-9 shrouds back over the barrel of your rifle concealing part of it inside of the CAR-9. This is what gives the illusion of a suppressed SBR and of course, no stamp is required. Keep in mind, this fake can is just for cosmetic looks and does not provide any sound suppression whatsoever. The CAR-9 should only be used with barrels with Carbine length gas systems.
