Turns heads at my MD range. Confidence in your hands – One of the best AR u can buy as a MD resident without paying for LWRC or G$. I was hesitant at first, but after owning it for 2 years, I can say I never had a single malfunction. I had guns that I don’t feel confident with, as in is wobbly, screws strip, or uses chinesium. This build combined with a AERO lower just is rock sturdy, and I know if I were to take it into a war zone, I will have a companion that won’t let me down. Also, the most important factor is that with MSF you have full customer support. You are not talking with some lady who sits at a customer desk all day, but rather the people who builds these. I will be buying more from them.
So Far So Goo – I have not yet been able to test fire this rifle yet. I did have a fit issue with the receiver lock plate. I had to grind down the top so that the charging handle would clear it to allow for function of bolt-carrier group. Otherwise this was nice and shipped very fast. I think Mid State Firearms is FIRST CLASS and a fantastic business!! I will certainly shop with them again.
Edit Previous Review – The previous review posted as one star was supposed to be five stars. I would give 10 stars if I could—these guys rock!
Love these guys.
First kit purchase and can’t complain! – Went with MidState as they were the best lefty kit I could find with options in the kit. Overall the kit was perfect. Had a minor issue getting the fire control group installed but once I got it together I was shooting good groups “out of the box”. Definitely recommend MidState to anyone!
