i was using my ruger the last few nights to shoot possums in a forestry block adjacent to a semi-rural/residential area. Completely legal in terms of shooting laws, there is VERY little wind there and even with a large suppressor the CCI Sunbsonics I need to cycle the 10/22's action are quite loud and noticeable from a suprising range. SO not wanting to bother or wake up any residents I switched to the winchester super X which is much quieter but will not cycle the action. I am happy with the more or less bolt-action-style of cocking after each firing, but being that the bolt isnt locked in place it does half feeds and jams up due to the bolt traveling back varying distances. AND SO MY QUESTION Like the M1As gas piston ability to switch between semi-auto and this pseudo-bolt-action mode, is it possible for me to make some kind of mechanism to hold the bolt shut hereby minimising the sound created by the shot? obviously the CAN is down to my engineering skills but I mean IS IT POSSIBLE TO HOLD THE BOLT SHUT while firing the 10/22 without it causing damage or any issues. I just dont want to risk myself or the rifle, so information would be great.
