Crosman MAR177 test report: Part 6

Crosman’s new MAR177 upper is big news!

Today’s test is shooting the Crosman MAR177 at 25 yards, both with and without the magazine. We’ll also shoot it with the best wadcutter target pellets and the best domed pellets to see what differences there are.

Rather than shoot the rifle myself, I let Mac shoot it this time. He is the better rifle shot between us, and I just wanted to see what the rifle would be like in his hands. He shot it off a bag rest at 25 yards indoors. Ten pellets were shot from the magazine, then another 10 of the same pellet were shot using the single-shot tray. Mac tested both domed and wadcutter pellets, so we get to compare the relative accuracy of both today. And the results did not turn out as I expected.

Crosman’s new MAR177 upper is big news!

Today, we’ll look at the Crosman MAR177 upper shooting domed pellets at 25 yards. I’ll be using the 10-shot magazine, so we’ll get to see that in action, as well. I’ll tell you right now that today was a learning day that spawned another report that’s still to come. Read on to learn what it is.

As you know, the Crosman upper receiver is attached to a lower receiver that I built on a Rock River Arms lower receiver shell. I used Rock River parts, and the trigger is an upgraded two-stage National Match trigger, also from Rock River.

Crosman’s new MAR177 upper is big news! This view shows the front sight properly oriented.

Today is the first accuracy test day for the Crosman MAR177 upper, so let’s see how this baby shoots. Blog reader Darth Cossack pointed out that I had mounted the front sight backwards in the last report, so I fixed that for today’s photo. It wouldn’t have mattered from a shooting standpoint, but we do want the gun to look right.

On this AR-15, both the front sight and the rear sight adjust for elevation, while the rear sight also adjusts for windage. The front sight requires a sight adjustment tool that I don’t have and didn’t see packed with the upper. You can also use the point of a 5.56mm military round, which I have an abundance of, but doing it that way is very laborious. I’m hoping the rear sight adjustments will take care of everything that’s needed.

Crosman’s new MAR177 makes a fine tactical target rifle when attached to an AR-15 lower.

Today, we’re going to see how the new Crosman MAR177 upper performs! Because this rifle is a precharged pneumatic, I used my Shooting Chrony Alpha chronograph to analyze the power curve. Though not absolutely necessary, a chronograph can eliminate a lot of shooting time and let you know how the rifle shoots on the first session.

The test rifle was showing a charge of just less than 1,800 psi when I started the velocity test. I chronographed Crosman Premier Super Match target pellets that Crosman sent with the upper for testing the rifle.

Well, when was the last time we had a discussion this large on this blog? You were talking on yesterday’s report and on the first part of this series, all at the same time.

And, we were talking apples, oranges, cinnamon wafers and pseudo-dadaism in the post-war cinema! All at the same time.

So, once more, I will attempt to state what it is that we’re trying to do. We’re trying to discover some things that, if applied in certain ways, will always help improve accuracy. As I explained to several readers, the artillery hold is one such thing. I didn’t invent it. I just gave it a name so I could talk about it, and people would understand what I was talking about.

No other single blog report has had the reception this one has! We have had readers awaken to discuss their favorite things and other readers say they are leaving the blog because they don’t want to read the lengthy comments made by enthusiastic readers who have been stimulated about this subject.

We also had a number of readers who failed to understand what this series will attempt to do, so perhaps I had best state it again clearly, so we all know. The purpose of this series is to discover those things a shooter can do to improve accuracy with an airgun. This is a quest to find out what works, as far as improving accuracy is concerned.

Testing 4 vintage 10-meter air rifles

Well it’s Friday again, and it’s time to have some fun. When I tested the TF 79 competition air rifle, I mentioned that I also shot several vintage 10-meter rifles the same day, just to make sure I was still able to shoot a good group. Well, we heard from a lot of readers who apparently like these oldsters just as much as I do, so I thought I would take today and report on how they all did.

I’ve owned most of the better-known classic 10-meter target air rifles over the years, but I didn’t hold onto them because I was always chasing some other dream. Long-range accuracy or big-bore prowess were always competing with these quiet target rifles, and there’s only a finite amount of money to go around. So, over the years I’ve both shot and given up some real vintage beauties.
