This report covers:
• Equipment to fill the gun
• Silicone chamber oil
• Diver’s silicone grease
• Plumber’s tape
• No such thing as Teflon tape
• A chronograph tells the whole story
• Other things?
Today, I’m writing this for the sales representatives at Pyramyd Air, who are always asked what else you’ll need when you buy a precharged airgun. Precharged airguns need some things to go with them to operate smoothly. Think of the batteries you always need for electronics. Are they included in the box or do you have to buy them extra?
This topic was suggested by veteran blog reader Kevin. I liked it because it gives me a chance to say some things to the new airgunners; better yet, it’s a great way to start a discussion among all you readers.
I will touch on the things about chronographs, which are near and dear to me, but I think my role today is simply to get the ball rolling. We have enough readers with chronograph experience that I’m sure they’ll share a lot of their own viewpoints — some of which may never have occurred to me.
What is a chronograph?
The term chronograph means different things to different people. To an horologist, it might mean a particularly accurate instrument (watch or clock) to record the passage of time; but to a shooter, it means an instrument that’s used to measure the velocity of a projectile. It still records the passage of time, but also performs an additional calculation to convert the results into velocity. As incredible as it sounds, we’re able to measure the speed of a pellet or bullet moving hundreds, or even thousands of feet per second with an instrument we can buy for as little as a hundred dollars.

At last, we’ve come to the day when I get to spend your money or suggest gifts for you! Knowing what an enabler I am, you must appreciate what a rush this report is for me.
Champion heavy-duty trap
I will dive right in with my first suggestion — a Champion Heavy Duty Metal trap. If you don’t yet own one of these, you need one. They cost $42 when I bought mine in the early 1990s, and time is a-wastin’ for you to get yours. Yes, they’re pricey for what they are, but this is the last trap you’ll ever need for any smallbore air rifle. It’s rated to stop standard-speed .22 long rifle bullets, so you know that nothing your airguns can toss at it is going to do any damage. Mine has uncounted shots on it, and it’s still in near-perfect condition — except for the paint. I’ve emptied about half a ton of lead from this trap over the years; and, yes, that was all melted down to be reused in cast bullets. The last 100 pounds of it is still waiting to be melted. This trap is big, heavy and hard to love — except when you’ve been using it for several years, and you finally realize what a tremendous piece of equipment it really is! Not for steel BBs!
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.
Heads up! Before you read today’s blog, I wanted to alert you to a special scope deal Pyramyd Air is running through GearHog.com. For one day only, they’ve slashed the price on a Leapers 4×32 compact scope with rings. The scope goes on sale Wednesday morning (9/21/11) at 3:00 A.M. Eastern. I can’t say for sure the exact minute that evening when it’ll go back to the regular price, so be sure to order early if you want it. Click on the Gear Hog link to get yours. There’s also an order limit of 2 per person. Now, on to today’s blog.
I need to be humbled periodically to maintain my perspective on things. Fortunately, for me, I was created with many imperfections that make frequent humbling a certainty.
I was taking a .22 semiautomatic rifle apart several days ago to clean the action, and I got to the part where you remove the last drift pin and all the major and minor parts fly apart like a satellite that’s been hit by a particle beam. No chance to see where everything went because they all got disassociated at the same time.
When this happens, I have several mantras to address the situation. No. 1 is I imagine the item was assembled by a 19 year-old girl named Tiffany, while she is also talking to her coworkers, drinking a Slurpee and texting her best friend. Tiffany can put this thing together in 27 seconds and can spot (without thinking about it) when part 51b has been reversed in its slot, which is good because Tiffany isn’t really into thinking.
