So I've got this bare muzzled VEPR K that I never got around to sending off for threading and after learning about the new Molot ban have decided it's time to remedy that when I happened upon this marvel:


Press-on Molot SVD type flash suppressor. One of the most effective flash reducing muzzle device. Classic look and time proven design.
Fits on any un-threaded barrel with 15.55mm diameter. 100% Manufactured by Molot in Russia. Recommended by many hunters and rifle enthusiasts.
NOTE: This muzzle suppressor is not threaded and has to pinned in to the barrel.

Are these good to go? What all is involved in pinning it to the barrel, something an end user can do or should be left to a professional?
