Found a Kel tec PLR-16 in 5.56, used, with some sort of truglo red dot (i think) scope sight thing, and a like back pack sort of sling for $450. It seems to be in good shape, needing only a decent cleaning. I cant afford it right now but its 90 day layaway so Im really thinking about it. Is it a good deal or no? Just wanted to get some imput from y'all as this is one iv never researched.
