its louder than a 20", a krink break does a hell of a better job at reducing the noise for the person behind it, not so much for in front

I had heard they also were used to slow the rate of fire when on "auto". That, because of the shorter barrel length, the cyclic rate of fire jumped up, hurting reliability. 'Course, under those circumstances, I guess leaving the barrel 14 or so inches long would make more sense than hanging a heavy 3.5" piece of steel on a 10.5" barrel. |
Reduces noise and concussion to a dull roar. They were very basic and inefficient suppressors. Due to the fact that they were welded closed at the rear, there was no way really to clean them. The expansion chambers would fill up with carbon and noise reduction became worse as time went by. |
| I have heard from a reliable source that they really were to increase reliability in cycling and that they reduced the DB's by 2 DB was really the coincidence that caused ATF to regulate them as silencers in the mid 70's. They actually do work OK on .22LR rounds as a silencer though. |
