1377 "Ultra Carbine" now complete!

I got out the tools and new parts this week and finished the upgrades on my 1377 "Ultra Carbine". The installation of the new aluminum flat top piston and valve that I got from A.C. Custom Parts went smoothly. Alejandro has very good instructions on his site on how to install his pistons and valves. If you just follow the directions, you can't really mess it up. I hear a lot of guys complaining about cut o-rings when installing them, but if you just debur the tube really well with some sand paper wrapped around a 1/2" dowel, you can't go wrong.

I haven't run any shots across my chrony yet, but judging by the pellet penetration in wood and by the increased noise I would say that my gun is now shooting ~50% faster than it was with a stock piston/valve. I'll get you guys some numbers soon to show the results. It dumps 15 pumps no problem. I haven't tried any more than that but I will just for fun when I break out the chronograph. I did notice that the first 5 or so pumps are much easier to do than stock. Once you get over 10 pumps the force required to pump the gun increases quite a bit as I expected it to.

I'm definitely going to have some fun testing this gun and my other 2 pumpers once I get the pistons/valves installed in them too. Thanks go out again to Alejandro for all his help and his excellent parts. You've taken my gun to the next level!

Here's a few shots of the gun now that it's finished. Have a great time shooting and go build yourself a custom Crosman, they are loads of fun!

You want performance? You got it!

Being that my home range is of limited distance(15 meters), when building my custom 13XXs I was never that concerned with how fast my gun was shooting. I figured if I could hit anything within my range accurately, that was more important. Because of that, I saved the power mods on my guns as the last thing that I would ever do to them. I finally have them where I want them cosmetically so now it's time to up the power!

I placed an order with Alejandro at A.C. Custom Parts for 3 aluminum flat top adjustable pistons, 3 aluminum flat top power modded valves, 3 power hammer springs with guides and a polished brass goody that will be coming separately. Everything came today and of course, I was like a kid on Christmas. Alejandro's machine work looks excellent upon inspection. I am excited to get these installed and see what my guns will put out with the upgrade. I will be posting some before and after chrony numbers for all you guys out there into the performance mods so stay tuned.

Thank you Alejandro!

The finishing touch on my custom Crosman 2250

Two weeks ago I finally ordered the last bit to finish off my custom Crosman 2250, some nice wood. I contacted Ralph Brown at RB Grips to purchase a Zebrawood stock insert and matching forearm. Well, today it arrived!

I couldn't wait to get it unwrapped and mounted on my gun so I could take a few pics to show you guys. I think they(the wood) came out really nice in my opinion. I wanted a wood to go well with the brass bits on my gun and I thought Zebrawood in high gloss would do the job well. What do you think? Here are a few pics I took of my now finished gun.

Thanks for the beautiful wood Ralph!
