10/12 Update: I have included a printed KAK sized flash can. Now instead of buying the KAK one, you can just print one and use a 1/2x28 to 3/4x16 thread adapter ------------------------------------------------- This is a baffled lid for a 5 gallon bucket. It is designed based on ATF letters on what constitutes an NFA item. The letter indicates that a suppressor is an NFA item if it is ATTACHED and PORTABLE. This item is neither attached nor portable in the intended format. It is attached to a 5 gallon bucket bullet trap that weighs over 50 lb. It cannot attach to a firearm. It is rated for 9mm and 22lr supersonic and subsonic.
