    Probably true on both counts.

    I drove out into the hills east of town this morning with a handful of mags and a variety of ammo. Let me start by saying that I'm out of rifle sight-in targets and all I have are big brown USPSA targets. I set up two targets and then shot for group at 100 yards. I shot in the prone using a tool box and a rolled up gun case as a rest. I used an Aimpoint and my Larue Poor Boy off my 6920 as an optic. I've got a Burris AR 332 on order and, if it ever arrives, it'll go on top.

    WOLF 55JHP shoots about like you'd expect. 2-2.5" groups at this distance. Speer Gold Dot ammo shoots a little better. I also took along some old DCM reloads and was pleasantly surprised to find that a 77gr Nosler with 23gr of AA#2230-C shoots about 1.5" at 100 yards. I was worried about the 1x9 twist and the heavier bullet. Also along for the ride was a box of 69gr Nosler loaded with 24.5gr of Varget. This stuff shot the best with several groups right at or just over an inch.

    After this, I moved my position back to 300 yards. Now, I don't have a laser range finder and this was actually 300 paces away from my targets. So it could be 275-325 yards for all I know. Anyway, I got back in the prone and commenced to firing 5-shot groups at this distance. At 300, I had to aim at the head to keep the rounds center mass. But I was surprised that the 69gr load still shot well. I had a number of groups that could be covered with the palm of my hand. The 77gr and 64gr Gold Dot stuff shot a little worse but still respectable with most groups running about six inches, give or take. I only fired one group of WOLF from here and I think I had something like 2 Alpha, 2 Charlie and 1 Delta at 300. Not bad for cheap crap.

    As I walked back and forth to check my targets, I took the carbine with me. I kept it loaded with WOLF and blasted at rocks as I made my way down range. Somewhere through my 2nd magazine, I had a failure to extract with a rim torn off the case. By this point, the chamber was pretty dirty and the gun was pretty toasty. I guess not even Ruger can make a gun that'll run 100% with WOLF! I fired a total of 150 rounds today bringing the total to just under 300 rounds through the gun.

    I gotta say I'm pretty impressed. The gun sure seems to want to shoot. I'm sure that with a target better suited for precision aiming, a lighter trigger and with a better rest, I could probably reduce my groups by 25%

    The wife's out of town and she took the digital camera with her. I'm aware that without pictures, this stuff more than likely never happened. But my word is good, isn't it? We know the answer to that!

    Amazing that the gun didn't spontaneously explode given some of the comments in this thread. Nothing like real world, actual experience with the platform before pronouncing judgment.

    I did burn my finger on the gas block if it makes you feel any better.

    Tokarev,

    Could you take a look at the buffer tube and see if there is any signs of carrier tilt? Also, take a look at the inside of the upper (in the channel where a gas key normally rides) and see if there is any signs of the cam pin dragging?

    Both of these are two of the common issues reported with AR piston guns, just wondering if they've been addressed by Ruger.

    Thanks.

    They are both present.

    I've got just under 300 rounds through the gun now.

    FWIW my Ruger already has finish wear just in the receiver extension just from Ruger test firing it at the factory. I haven't shot mine yet. Here's what is looks like.

    Me thinks this thing is going to have carrier tilt issues unless one uses a Seth Harness anti-tilt buffer.







    I changed out the lower receiver end plate for a used DD QD one I had, added a DD rail mounted QD point, a Vickers Combat Applications Blue Force Gear sling, a DD forward grip and some Magpul XT rail covers and ladder covers and a AAC Blackout M4-2000 flash hider/suppressor mount. Some of my co-workers (hunters and people who don't train nor compete) wanted me to leave it 100% stock. I asked how can I run drills that way? They looked at me like I was speaking a foreign language that they couldn't understand. Some people just don't get it...

    Have you attempted to clean the piston yet?

    I don't know who said that in this thread (know it wasn't us).

    Then again, we also do not recommend BM AR's for serious use (and they do not "explode" when shot).

    A couple hundred rounds through this gun means that it runs as well as an Oly Arms AR.

    Come back and talk to us about how well the gun is holding up after 4 or 5 carbine schools.

    Our personal opinion on the Ruger is based off one of the best firearms engineers in the industry examing the weapon, talking to Ruger about their design and making suggestions on how to improve it.

    I pulled the regulator plug off this afternoon. It took a little finagling but it did come out. I can imagine that if this piece was left in place for an extended period/round count, it would become necessary to pry it out.

    Ruger should move the hole in the regulator so that it is horizontal rather than vertical in the disassembly position.
