My new-ish Noveske SPR upper. I got a free lower to go with it when I ordered. There are parts on order for the lower.....now all i need is glass, a can, and a metric shit ton of ammo. I took my EOTech off my other upper to play around with this one and with EOTech and magnifier it was holding a 3 inch group at 100, not great I know, but with the EOtech, the dot was covering up the target, and I wasn't really practicing proper form. I was shooting BH remanufactured 77gr BTHP. Has anyone gotten a chance to chrony that stuff from an 18" barrel?
