My agency, a small 20 man department (including reserves ) is apparently looking to supply all full time officers with patrol rifles. This in itself is good for obvious reasons...However...here is the hitch. The rifle in question is the Rock River LAR40..a .40 caliber AR type rifle. I know nothing of these rifles...good or bad. Does anyone have any first hand dealings with them?? Our firearms instructor does not want to issue .556 caliber weapons for whatever reason...I know..I know...I've argued it till I'm blue in the face, but I am glad we will maybe get new patrol rifles. I just don't want to be saddled with a crappy weapon that will be more trouble than it's worth. Any usefull info would be greatly appreciated.
