Well I finally got to the range today to shoot my upper. Let me tell u , this thing shoots AWESOME. When I unloaded evything I discovered I forgot my ammo box
Good news I had a couple of loaded mags in my truck. Bad news they were both loaded with Tulammo 55 gr fmj. I keep em in the truck in case I get stuck with no ammo( just like today)
More good news, this upper ate the Tulammo perfectly, I was impressed to say the least. Unlike a lot of folks here it doesnt bother me at all to shoot steel case. I hate an upper that will not shoot it.
Kudos to Rainier Arms for putting together a nice upper.
