Arsenal M5 Range Report – 17 Dec 2003
I went to the range again today.
My intent from the start of these test has been to sight-in at 50 yards, then check the accuracy at 100, 200, and 300 yards, but today I did not make it past 100 yards either.
I was mistaken about the Robinson Arms (RA) scope mount. It does fit on the VEPR. It has a much longer lower rail then other AK mounts, requiring precise placement, and has a tighter fit. The scope mount rail on the VEPR rifle also has a longer lower rail than is typical. I suppose it makes for a more solid mount, but is harder to install and dismount. You would not want to do it in a hurry, and might need a table edge to get it off. The elevation locking screws were extremely handy at the range. When I moved the mount over to the VEPR the point of impact was so low I was splattering mud on the front of the targets, but it was easy to loosen two screws and lower the front of the scope mount.
So along with the M5S and the RA mount with the BSA 6-24x Scope, I also brought along the VEPR K, as well as a cheaper Russian scope mount with a Tasco 3-9x zoom attached.
The ammo was again Winchester Q3131A Lot TG32 and the magazines were Bulgarian waffles. The temperature was 49 degrees.
Well, I blew it. At 50 yards I set up two targets that have 5 aiming circles each. I crossed over a few times so I don't have legally precise groups to report. Some of the groups have extra holes which I am counting for maximum group size, but I am not listing groups with fewer than 5 holes.
Arsenal M5S, BSA scope at 24x, 50 yards:
2 3/4”
2 1/4”
3 1/2”
3”
2 1/4”
3 1/4”
2 1/2”
When I moved the target to 100 yards I thought my shots really spread out. Since I was still using the targets with 5 aiming circles, there was just not enough target space available.
Arsenal M5S, BSA scope at 24x, 5 shot groups, 100 yards:
4”
7” or 2 1/2” if one flier excluded.
8” or 3 1/4” if one flier excluded.
3 1/2”
6” or 2 1/2” if one flier excluded.
The rest are so spread out and off target I can't tell what is what.
Without my ruler those big groups looked just awful through the spotting scope. I thought I had a problem. It was not until I got home and measured that it looks better. The strange thing about some of the fliers is that they happened when I thought I had near perfect shots. I was steady, on target, perfect trigger pull, surprise break while precisely on target, and off it goes to the side. A real confidence breaker. I am getting nowhere near the 2” MOA groups this rifle was supposed to deliver.
So I changed scopes and mounts.
Arsenal M5S, Tasco scope at 9x, 5 shot groups, 100 yards:
9 1/4”
6 1/2”
5”
8 1/4” - minus one missing shot (4 shot group).
Yikes! Very, very bad. What happened? Is something wrong with the mount or scope? Going from 24x to 9x should not do this. But without my ruler it looked only a little worse than the previous results. I thought I had a problem, so switched rifles to compare both rifles and scope/mount.
It was getting dark and I had to leave soon, so I was a bit rushed, and not quite as careful as before for these last shots. But I also noticed the VEPR is a much steadier rifle on the shooting bench. It felt much more solid and locked on target.
VEPR K, BSA scope at 24x, 5 shot groups, 100 yards:
4” or 2” if one flier excluded.
5”
VEPR K, BSA scope at 24x, 10 shot groups, 100 yards:
6” - mostly spread vertically. No more than 2 1/2” L/R.
5 3/4” - eight shots in 2 1/2” group!
So the overall best results at 24x if fliers are excluded:
M5 – two 2 1/2” groups.
VEPR – one 2” group.
The best results if fliers are not excluded:
M5 – 3 1/2”
VEPR - 4”
The worst results:
M5 - 8”
VEPR – 6”
There were no malfunctions of any kind with the M5. The VEPR experienced 4 ejected live rounds. When I had about 3-5 round left in a magazine I would get the dead mans click. When the previous round was ejected, the next live round also flew out of the rifle as if it was ejected spent brass. The bolt then closed on an empty chamber. I need some clues on this folks!
Comments, suggestions, and experiences are welcomed!
