Re: Suppressor for TRG-22
Have an A tec TMM-4 on my Steyr Elite 08. This is a 'modular' silencer. ie you can add or remove baffle units as you like. - it is also a 'telecoping' unit, where the initial expansion chamber goes backwards arround the barrel.
Recoil reduction...at least as good as the original 3 port muzzle break.
Accuracy- since that was what this rifle was for...I experimented with different number of baffles. Came down to the minimum (base unit/main expansion chamber + end unit) this gives me one internal break, a big expansion chamber, then a baffle, a small chamber and then the end cap. 10 shots into 1.8" at 300m with Norma dimond line ammo (calm day). Worst group with one intermediate baffle as 2.8" and with all baffles in place was about as good as the shortest option (but then gun didn't fit in gun cabinet or carry case).
Not the quietest option, but no dust signature, good break effect and quiet enough to shoot on an out door range with having to have ear muffs. (about as load as a .22 revolver now)
