Finally got my ACR to the range last weekend. My main objective was just to get a few rounds through the rifle to see how it handles and to zero the iron sights.
Initially I set my target up at 25 yards, fired a group in the center and then the corners with my friend spotting. No impact, no idea for about 2 mags.
I moved my target up to 15 yards and realized that I was shooting about 2 feet low. I have to admit that I hadn't looked too closely at the MBUS sights until then. I didn't realize that they don't have elevation adjustments on the rear sights like normal AR iron sights. I don't know if it was just me and my friends, the fact that they are new, or thats how they always are but we could not change the elevation on the front sights with a bullet as shown in the manual. It just ended up tearing up the jacket of the bullet. I had to go back to my car and get a leatherman so I could use the pliers to crank them down. Once I got that taken care of I was able to keyhole groups in the x ring of my targets at 25 yards.
I was using Federal 55 gr XM193 with Pmags and USMC issued metal mags. The rifle ran flawlessly, no malfunctions, and it locked back on all the empty mags. One of my friends brought his Rock River AR and picked up some Remington hollowpoint 223 ammo for it. I think 40 gr. He could not feed that ammo from a mag at all, the first attempt jammed a bullet deep into the brass. We switched mags and my ACR ran it fine so we traded ammo so he could keep shooting. He only had 40 rounds compared to my 500.
The main takeaway for me on this trip was learning about the MBUS sights. I wasn't planning on getting optics for this rifle anytime soon since I'm fine with traditional iron sights but I think I changed my mind. I'm not saying I hate the MBUS sights but I have learned their limitations. They are folding backup sights that lack the ability to make quick elevation changes or have different size peep holes. They do what they are designed to do, no more, no less. I could get Troy sights but I might as well spend more, get optics and use the MBUS sights as they are intended, backups that probably won't get used much.
I plan on going again next month and took off the barrel when I cleaned the rifle to see if the sights maintain their zero. The range I go to only goes out 100 yards so I'll see what kind of groups I can get. On a side note one of my friends brought an Eotech we were going to throw on the rifle after I zeroed the iron sights. It hadn't been used much and had been sitting in a closet without batteries for a few years. We scratched at the contacts and threw in new batteries but couldn't get it to turn on. I'm not a big fan of electronic sights and this didn't help.
This post dragged on longer than I expected, I hope it didn't feel like a waste of time reading it.
