Reduced Target for 12 Feet
I recently picked up a MAR177 to practice with during the off-season. I wanted some targets to mimic the SR-1 target at 12 feet but I could not find a commercial target that would be the right size, so I made one.
The math isn’t as complicated as it seems. Take the distance you want and divide by the distance of the target you are reducing. In this case 12/300 (feet) which is .04 then multiply that by the size of the target you are trying to reduce.
The black of a SR-1 target is around 6.5 which reduces to about .25
The formula looks something like this.
(x/y)z
X = the distance you are reducing the target for.
Y = the distance the target you are reducing is designed for.
Z = size of target you are reducing.

Crosman MAR177 AR-15 Upper Review
Several years ago Crosman introduced the MAR177 upper. It’s a match grade A4 style upper that fits on a standard AR-15 lower. The advantage, to me, is this upper fits on the same lower I use for High Power. So it has the same weight, same Geissele national match trigger, and overall feel as the rifle I use for High Power.
As far as the upper itself, i’ts solid and easy to use. It comes with a ten round magazine (they call it a clip). I use a single feed tray as I intend to practice mostly on slow fire off-hand. It is not semi auto so there is an AR-15 style charging handle which is pulled between shots to reset the trigger and air system.
The MAR177 is a Pre-Charged Pneumatic (PCP) so it has an on-board air tank that needs to be charged with either a pump, a scuba tank, or a special compressor. I picked up a Benjamin hand pump which resembles a bicycle pump. While cocking a Red Rider BB gun between each shot, filling the tank using this pump can be a bit of a work out. I figure that I can work on my upper body strength and my off hand at the same time.
I intend to use this to get some indoor trigger time over the winter break before the spring matches (tomorrow’s high is 12 degrees). Since a trip to the range tends to eat up the better part of the day, the MAR177 allows me to squeeze a few rounds in any time I can spare a few minutes. This should cut down on the excuses I make about my lack of practicing.
While I do not intend to take it to any air rifle matches, at least not just yet, I impressed with its performance during some quick range time this evening.
This wouldn’t be a fair review if I did not mention the out of the box issue I had with the MAR177. Upon delivery the upper would not hold a charge meaning there was a leak behind the gauge. However, I contacted Crosmen who responded within 30 minutes with a shipping label. They had it replaced and back to me working 100% in 8 days round trip. Which frankly is better than the service I have received from some well regarded firearms manufactures. Despite the out of the box issue I had, I would not hesitate to recommend this upper to anyone looking to get some more trigger time.
Freezer Match 2015
Took the M1 Carbine out for the freezer match. This is a “fun match” our club runs, any rifle, any sight. I took out my M1 Carbine as had not had much trigger time with it yet.
It was a nice crisp day in the low 30’s and a little overcast. The match was a 40 round off hand match. I had never so much as fired my carbine off hand so I did about as poorly as I had expected to do. But this was a good start towards getting the hang of shooting this thing.
Unfortunately on my last target the lug on my M1 Carbine flat bolt sheared off so I wasn’t able to finish the match. There are picture below of the broken bolt. It seems I have some work to do on this carbine before Perry.
All and all it was a great match, there was chili, coffee, and door prizes with the benefits going to charity, I’ll need to keep practicing during the off season. The National Matches will be here before I know it!
The Broken Bolt:
How To Use a 1907 Sling
A sling is more than just a strap to carry the rifle. Properly using a sling can provide a sturdy shooting platform.
I prefer a Ron Brown 1907 sling. While slower to sling up, I feel more stable with a 1907 over a web sling.
The sling pictures is a John Weller 1907 I picked up at Camp Perry a couple years ago. Sadly John passed away since then and these slings are no longer made. Ron Brown slings, sold by Creedmoor sports are the best slings on the market. They are thicker more sturdy and stretch less than most other slings.
First you will need to have your 1907 installed correctly. CMP has a detailed write up on this below that can help get you started. However, they do it wrong. Put the frogs facing in towards the rifle. As you’ll see below this will put the frog on the top when slinging up which is easier to manage and less likly to slip.

Once the sling is set up correctly remove the frog on the short strap (aka tail) of the sling from the looped long strap. Then pull it free from the rear sling swivel.
Adjust the sling so there is a large enough loop to fit your arm in. Pull the upper keeper away from the frog so that it is easier to adjust.
Turn the loop clockwise so that the loop faces you. The frog should be facing more or less to the left or away from the rifle. Be careful not to do this step twice in haste and get the sling twisted.
Then stick your support arm through the loop.
Push the sling up your arm as far as it will go. There is some amount personal preference here. The key is to do it the same every time. I use the pad on my jacket as a reference point.
Once you have the sling all the way up draw it as tight as you can. I do this by pulling on the lower half of the loop with my left hand and holding the upper half of the loop with my right hand.
Once the sling is nice and tight, slide the upper keeper all the way down to the frog which will lock it all together.
Then you are ready to go. Place your support hand over the sling and grip the stock.
You will need to determine what the best length and support hand position Is for you. Rig up, get into position and dry fire a few times until you feel comfortable.
My left handed wife informs me I should add that this depicts a right handed shooter.
