Summary

Today’s test will be interesting to me because I have no clue how the Springfield Armory M1 Carbine airsoft gun shoots. Usually I have some idea going into a test and can select the right ammo to suit how I think the gun is going to perform. This time I have almost nothing. The only things I do know is the gun is powered by CO2 and also the same gun shooting BBs did very well.

Part 2 testing

We learned in Part 2 how fast the test gun shoots. It’s on the high end for the recommended 0.20-gram BBs. It seems to slow down to a useful velocity with 0.30-0.36-gram BBs (407-387 f.p.s.). I am curious to see what they look like on paper.

Today’s test

I shot off a sandbag rest at 10 yards for this test. Five BBs were shot at each target, unless the results seemed to warrant shooting 10. That did happen in a couple instances, as you will see.

One thing to remember about this airsoft gun is there is no adjustment for elevation. Windage yes, but the elevation is fixed. That will play into the test results, as you will see.

I’m using the sights that come on the gun. It really isn’t suited for mounting any other sights, but these are fine.

0.20-gram TSD Tactical BBs

The first to be tested were 0.20-gram TSD Tactical BBs. This is the recommended BB weight for this airgun. The first BB hit in the 10-ring, so I shot the other four without looking again. Three of the remaining four BBs hit at the top of the target paper but the last BB was lost. The four BBs that hit made a group that measured 3.103-inches between centers. I can’t recommend this weight BB for this airgun because the BBs do not correspond to the sights and they spread out too fast. Yes, downrange they will drop a little, but this isn’t the level of accuracy I want in a skirmishing airgun.

The 0.20-gram BBs did not group well. The four that hit the paper are in 3.103-inches between centers at 10 meters.

0.25-gram Valken Accelerate BBs

Next up were some 0.25-gram Valken Accelerate BBs. These were quite a bit better than the 0.20-gram BBs. In fact, after 5 shots the group was so good I photographed it in the target trap and returned to shoot 5 more.

M1 Carbine airsoft 0.25-gram group
The first five 0.25-gram Valken Accelerate BBs made a very small group. I didn’t measure it, but it’s just over an inch between centers.

The second five opened the group a little, but nine of the ten BBs are still in a small area. All 10 are in 2.416-inches at 10 meters.

M1 Carbine airsoft 0.25-gram group 10
All ten 0.25-gram BBs went into 2.416-inches at 10 meters with nine in 1.148-inches.

0.30-gram ASG Blaster Devil BBs

Next to be tested were five 0.30-gram ASG Blaster Devil BBs. Would they group even better than the 0.25-gram BBs? The only way to know is to try them.

The first BB hit inside the 10 ring, but all five BBs went into a group measuring 2.293-inches between centers. With the way that the 0.25-gram BBs shot, I felt this BB was not right for the airgun.

The 0.30-gram Blaster Devils did not do so well. Five are in 2.293-inches at 10 meters.

0.36-gram ASG BBs

Bob Li of ASG sent me three additional heavy BBs to test in airsoft guns. The 0.36-gram one will be tested next. The first 5 BBs scored 49 points with 3 Xs on the 10-meter target. So I took another picture of the first five shots.

The first five of the 0.36-gram BBs gave such good results that I photographed them in the target trap.

I decided to continue this group as well, and this time it really paid off. Ten shots scored 99 points, with at least 7 Xs!

M1 Carbine airsoft 0.36-gram group 10
Ten BBs are in a group measuring 1.342-inches between centers at 10 meters! The score is a solid 99. This group did not enlarge with the final five shots.

No lag time!

This is the sort of accuracy I have seen with some sniper long guns in the past. And the good thing is I noticed no lag time between the shot and the impact on target. This BB would be a good choice for skirmishing with this M1 Carbine.

Continue?

At this point in the test I felt I had found the best BB. But I had others that were even heavier. Should I continue? Well, since this is my last test of this airsoft gun I figured why not?

0.40-gram ASG BBs


None of these ASG heavy BBs have a name, so I’m just identifying them by their brand and weight. This 0.40-gram BB is a weight I have never tested before. And the first five went into another nice-looking group.

M1 Carbine airsoft 0.40-gram group first 5
Here we go, again. The first five 0.40-gram ASG BBs made a perfect score of 50 with 4 Xs!

When I completed the group there were 10 BBs in 1.493-inches at 10 meters, with a score of either 98 or 99.

M1 Carbine airsoft 0.40-gram group 10
All 10 BBs went into a group measuring 1.493-inches between centers at 10 meters.

There was no audible lag time between the shot and impact on target with this BB, either. At this point I felt the best BB weight had been found, and it is 0.36-grams. But I also had a 0.43-gram BB on hand, so why not test it?

0.43-gram ASG BBs

This is the first BB that had an audible lag between the shot and impact on the target. The first BB went into the X-ring, so I wondered if this would be another hyper-accurate one. But as I shot I could see the other BBs hitting above the bull. In the end five BBs went into a group that measures 2.886-inches between centers. Clearly this BB is too heavy for the Carbine’s powerplant.

The group of five 0.43-gram BBs measures 2.886-inches between centers at 10 meters. Too heavy for this airgun!

Discussion

The lack of an adjustment for elevation makes selecting the right ammunition more important for this Carbine. Remember I shot at 10 meters, which is 33 feet. But in a skirmish the Carbine might be used out to 75 or even 100 feet.

This test does not establish the final accuracy of the Carbine, but it points out that the gun is accurate. I did not adjust the Hop-Up because I didn’t have to.

Summary

The Springfield Armory M1 Carbine is an accurate airsoft gun that performs quite well. It mimics very closely the BB gun from the same people.

I do think Pyramyd Air should consider recommending a 0.36-gram BB for this gun. The performance is so much better!

Higher-end airsoft guns are not Pyramyd Air’s mainstay products, to be sure, but there are probably many airgunners around the nation who have a use for an accurate airsoft gun like this. If so — here it is!
