Heads up AR shooter's I had the opportunity to try out BT's new BT-15 at the IFAMA show in Nampa this week and ran some rounds through it at a demo afterwards. This is a tightly built piece of equipment with a nice slim forend that is lightened up so more weight can be put in the barrel. These are extremely well built with 7075 billet machined upper and lower perfect anodized surface and hard Ano not the cheap cover Ano The trigger is worked over so it is clean break with no drag.The one thing that jumped out first was there was no buffer noise when firing the weapon recoil was soft shove not sharp slap as with some buffer systems. Check em out you won't be sorry. http://www.boisetactical.com/
