[i][/i]I enjoy shooting AR rifles & I like the 17HMR cartridge so I ordered a Ray-Vin 17hmr upper with a 18" threaded fluted barrel & had him put on a Diamondhead 10.75" handguard. Then I built a dedicated Black Rain lower with Magpul stock & Geissele trigger. This is one fine looking AR and what a blast to shoot. The upper receiver is a side charge & it does not use a gas block. I've got 2-14 & 2-10 round mags. for it. At 100 yards it will shoot .5 moa with certain ammo and is an awesome small varmint gun. Last week we put 10 sporting clay, clay targets at 220 yards on the burm & broke all in 10 shots. I shoot 200-300 rounds before I need to run a bore snake through the barrel. SWEET! Ammo: $10 to $12 per 50 on sale, what's not to like. I just wanted to share this with anyone who likes to shoot no recoil quiet AR's. My wife & grandson just fell in love with it.
