Was not one of the tested cans from the trials that were run, If we had gone with the best preforming can from those trials it would have probably been the OSS one selected, as it is they went with the low hanging fruit option.
It is what it is and is better than no cans, I suppose, which is the way it was looking for a while. When people kept trying to make "Hearing Safe" the major selling point....Once the item was sold to the decision makers as a lethality/ capability improvement they were all on board, when it was just being brought up as a safety device, not as many thought them required, just issue ear plugs....
The new service rifle is going to be a pig, As it is a 16 inch barreled, Quad rail equipped HK 416 with the new SCO ( Trijicon 1-6 VCOG won the solicitation), PEQ-16, grip, and suppressor hanging off of it.... Personally, I am not totally sold on the M27 for everyone but, well, I'm not the decision maker, it does what its told and shuts up and colors sometimes.....
