Interesting clips of the DeLisle Carbine on You Tube, this is just one.scotsgun said:We experimented with a couple of fully suppressed rifle designs when in the army and as others have stated, the ammo has to be subsonic to make it worthwhile.
My lasting impression was weight like you wouldn't believe! It was like carrying the GPMG all over again and pretty much as cumbersome.
Added to that, the rounds had a balistic curve like a rock falling from a cliff and are really only of use out to 200yds or so. The russians have a few which are intended more as aids to close quarters sabotage, etc.
We did have an excellent little rifle called the DeLisle Carbine - there are still a few hiding in armouries, if you know where to look. It only shot the 45ACP round but is surprisingly accurate and very, very quiet.
