Pick up one of the flash suppressor/muzzle breaks for the regular barreled mini that has a sight on it is it madsen? that makes them? shorten the barrel a sufficent length that when you install the suppressor you return the overall barrel length to 16 1/4 inches, remember to crown the barrel. and make sure you pin the supressor on. Pinned on the batfe considers it a permanent part of the barrel. You will need to open the suppressor up a bit for it to fit as the barrel is stepped and the suppressor is made for the narrower muzzle.To be honest, I didn't care much for it when I got the first one because I was disappointed with the accuracy. Only after having it rebarreled approximately 10 years ago with a heavy barrel did I come to love the rifle. Sub MOA with decent ammo (no handloading), It is good that they have addressed the accuracy problem in the newer rifles. They should have done something about it during the original development of the rifle and more people would like it today. My second Mini is not that accurate but rebarreling is too expensive to have it done to both. Despite thousands of rounds of various ammunition, not one failure has ever occurred.
