Ruger AR-556 report

garryc · November 22, 2015, 01:57 PM

I took the Ruger out yesterday. I put on the detachable Leapers 4x AR scope. I was firing reloads 27 grains Ramshot Tac with a Hornady 55gr FMJ. I fired on a grid target. The ammo is loaded in mixed head-stamp, much LC but with commercial also. I selected rounds with the same head-stamp.

After I broke the trigger a few time to get the feel of it I fired 3 rounds from a bench rest at 100 yards. Those rounds went 14 inches low and 8 left. Those 3 rounds fell in a 3/4" group.

I turned the scope up until I thought it would be parallel to the grid. I fired three more, which again went into a 3/4" group. Now that I was parallel to the grid, but off its left side, I turned the scope up to parallel the bullseye.

I fired 3 more and they went just over an inch. I turned the scope into the bullseye and fired three more. Dead center and a 1-1/8th inch group.

All this was in just a few minutes so I let the rifle go cold. I then fired three more but did not select the same head-stamp and they went around 1-1/4 inches.

These are cheap bullets bought in bulk and the rifle did that with them. Not target ammo by any means, just blasting ammo.

It is nice all they companies are producing AR's at under $600.

I picked up a Ruger AR556 this fall. Quality appears to be good. Reliability with the three loads tested was 100%. Groups with Hornady 75g bthp match ammo averaged 1" at 100yds. I used it to take a nice fat doe this hunting season. I couldn't be happier with the rifle.

For a budget AR this rifle would be my pick. It has nice features for the price. I am thinking about picking one up eventually just as a backup.

Looking at the specs, from what I understand the barrel diameter on an M-4 barrel behind the gas block, under the hand guard, is suppose to be .72. The Ruger's is .85. Wouldn't that make it a medium contour barrel?
