Range Report: RRA AR-15 Pistol

Finally had some time to process some video. Here’s a quick highlight reel of the RRA Pistol testing:

You can see the different groups at 25 and 50 yards. This is firing with the EOTech and a variety of good .223. Since this is primarily a sub-50-yard weapon, I’m calling this acceptable accuracy.

Down the road, I’ll mount the Leupold Mark AR on it just to see what the short barrel is capable of at longer distances.

New Toy! AR-15 Front Sight LASER

UPS dropped this off for me yesterday: Leapers UTG Removable Front Sight Tower with Red LASER.

I had been looking for a laser solution for the RRA AR-15 Pistol for some time, and was having difficulty finding what I wanted. The AR pistol is a flat-top with a free-float tube, and I didn’t want to go through the expense of replacing the free-float tube with a quad-rail. The only thing I could find was optics that had a laser built-in, like this Sightmark. But that Sightmark had poor reviews, and the laser isn’t adjustable, and that just won’t do.

I had about given up when I found the Leapers sight on opticsplanet.com. I was VERY skeptical – Leapers is known for its cheap Chinese crap, and the $29.95 price tag only reinforced my skepticism (looks like they bumped the price up to $34.95).

But I figured what the heck, it’s only $30.

It came in a fancy box with die-cut foam to hold all the individual little parts, including separate holes for each battery.

While that’s pretty neat and all, it reinforced my skepticism even further – figure that’s an easy $3 just in packaging. How cheap is this thing?

As it turns out, I was pleasantly surprised. The sight tower and mount seem solid enough, as does the manner in which the laser is mounted. It came with batteries, a tiny screwdriver for adjusting the laser, and an on/off tailcap as well as a remote pressure pad (which I don’t intend on using, but I know a lot of folks will like it).

You can see the tiny brass screws for adjusting the laser. They are very easy to turn, which worries me a little – they may require some loctite down the road.

I went ahead and lined it up with the EOTech dot at about 20 feet. I’ll take it outdoors later on and zero it in properly.

The dot is pretty large. This will be fine for my purposes – I wanted something I could use close-range, very quickly, in an emergency situation.

Here’s the dot on the wall about 7 feet away:

It looks HUGE in that picture because of the refraction on the white wall. In actuality, it’s close to 1/16″ in diameter at that distance.

We’ll get this rig out to the range to make sure that laser will hold a zero.

Happy shooting.

Rock River Arms AR-15 Pistol

Meet the RRA LAR-15 A4 Pistol.

This particular pistol is chambered in 5.56 NATO. It has a 7″ Chrome Moly 1:9 twist barrel on a flat-top upper with a free-float tube. This came from the Rock River Arms factory with a Hogue grip and RRA’s Dominator2 EOTech mount.

The Dominator2 allows co-witness of the iron sights with an EOTech holographic weapons sight. Seems like a good chance to try out the EOTech 551.

This one is still pretty new to me. I’ve performed the barrel break-in and I’ve zeroed the iron sights and the EOTech, but that’s about all. We’ll run it through its paces as soon as we’re blessed with some decent weather.

Happy shooting.

Rock River Arms Mid-Length A4

Here’s one of the rifles you’ll be reading a lot about on this site. Meet the Rock River Arms mid-length A4…

From the factory, this fine AR-15 rifle features a 16″ chrome-moly barrel with a 1:9 twist, flat-top upper, standard mid-length handguards, a 6-position collapsible stock, and RRA’s standard heavy trigger.

In the photo above, you can see that we’ve already made a few changes to it. The standard handguards have been replaced with a two-piece picatinny rail system from Midwest Industries. A mil-spec buffer tube has been installed, as well as a Magupl MOE stock. We’ve also outfitted this rifle with a Surefire M900A vertical foregrip weapon light.

What we really want to do is see how well this gun can shoot. To facilitate that effort, we start by modifying the AR-15 to help the shooter fire it more accurately.

First is a Timney Trigger set to a 3-pound pull.

Next, in order to eliminate our human error as much as possible, we install a Leupold Mark AR 3-9×40 scope on Burris Xtreme Tactical rings.

More on the barrel break-in, cleaning, and firing of this fine weapon is to come.

Happy shooting.
