any one been using the blood viens? i bought some just to check them out and cuz they are way to easy to put on but holly crap am i impressed. my groups litteraly grew tighter as advertised, one of the very few times a product does as addvertised.
ill need to double check, i was actually wondering how much of a diff they will make when shooting past 40. im headed to the range here in a bit and will find out.
