The Kel isa(PLR-16)Pistol Long Range.I put a MB on it and if you dont have hearing protection on youll feel like you just blew out your ear and there bleeding...trust me....
Some of the guys at the range blew me off when I told em to cover there ears,they go its only a .223 how loud can it be....too loud I guess.I think I will take the MB off this summer,it sure helps tho....Iam good out to 150 yrds with it on bench..
