Range Report: AR-15 Front Sight Laser

Great weather today. Got to try out the new laser.

This was a bright, sunny day, and I was shooting at 25 yards from a rest, not looking through the sights – I was basically sitting up straight and aiming solely with the laser. I couldn’t make out the dot on the orange targets, so I improvised a little to have the dot on the white freezer paper.

Adjustment was simple with the brass screws. However, as I had feared, the adjustment screws are just too loose to hold zero. The laser started wandering to the right after a few shots, causing shot placement to go left.

A little loctite on the threads took care of that. Unfortunately, all I had on hand was red (stronger) loctite. I do NOT recommend this… use the blue loctite.

Some loctite on the adjustment screws was all it needed.

While giving the loctite a few minutes to set up, I sprayed a few gray spots on the paper to help me see the dot.

After another adjustment, I was able to shoot the group below. Also, this will give you an idea of the size of the dot… Looks like it’s about 1/2″ at 25 yards.

All-in-all, I’m pleased with this purchase. It does exactly what I wanted it to do.

Happy shooting.

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.

Rock River Arms LAR-15

Rock River Arms LAR-15

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.

Savage Model 10 Tactical

This is a Savage Model 10 Tactical.

This Savage is my tack-driving 223. I traded a lightly used Remington 870 Express for it in 2008 – by far the best gun deal I’ve ever made.

This bolt-action .223 is a single-shot with a follower. It has a 1:9 twist heavy barrel with a target crown, free-floated in an HS Precision stock, bedded action, and a sweet trigger job that consistently breaks clean at 12 ounces.

I’ve topped this rifle with a Nikon Monarch 4-16×42SF scope. I hope to upgrade the scope to a Zeiss Conquest here in the near future… this outstandingly accurate rifle deserves outstanding glass.

When i first picked up this rifle, it was pretty dirty. I spent some time cleaning what looked like a couple years worth of powder and copper fouling out of the barrel. The Model 10 Tactical came with rings on it, so I rummaged through a drawer and found an old, beat up Tasco 4x scope to slap on the Savage and took her to a local rifle range the next morning.

I set up at 100 yards. After a quick bore-sight, I reached in my bag to get some rounds to zero in the beater Tasco. Alas, in my haste, I had forgotten to bring ammunition with me.

Luckily, a couple other fellas at the range were testing some of their .223 loads, and offered me some of theirs.

The first guy had some 55g Noslers loaded up in new brass that he gave me to get a zero. The first shot was about 2″ high and 1/4″ to the left of the bullseye. Gave the Tasco a click to the right and tried one more, and it was right where it belonged – 2″ directly over the bullseye at 100 yards.

The second fellow range-goer had loaded up some 52g Sierra HPBT bullets in some once-fired brass. He wasn’t having very good luck with his ammo in his Thompson Contender. I shot two of his rounds at my same target and slightly widened my earlier hole. The first gentleman was incredulous, so I allowed him to shoot the rifle. His shot widened the same hole to just over 1/4″. Then the loader himself had to try it out – his shot made our three-person five-shot group 3/8″.

So we had three different shooters make one jagged hole with 5 rounds of 223 at 100 yards shooting a used Savage Model 10 with a beat up Tasco scope on it using two different kinds of ammo.

The gentleman with with the Sierra loads was kind enough to share his recipe:
52 grain Sierra Match BTHP, Winchester primer and case, 24.5g H335.

We’ll visit this fine rifle again to see what it does with some real glass on it… and many, many different loads.

Happy shooting.
