    Custom barrels

    Have been offline for a while tinkering with other projects, but did want to give a quick report on something I learned from happenstance. Pulled out my Crosman while visiting my son and he showed me up with some darned fine shooting. After I left he ordered me a tin of pellets from Amazon just...

    Custom barrels

    Blackbirds are migrating through for the spring and are cleaning out my wife's birdfeeders, so I pulled out the carbine to take care of business. Afterwards, I started re-calibrating and now it fires readily-available and economical Crosman Premiers better than either RWS or JSB wadcutters. Will...

    Custom barrels

    Ordered two eleven inch air tube extensions from Mac1 today, but he is out of the bulk fill caps. Why couldn't I just install a foster valve in my existing cap? It's already drilled and the fosters have a threaded end so it should be pretty straightforward if I knew which size valve to order...

    Is a Foster a screw on or quick disconnect? Do all compressors have the same fitting? Have you ever chronographed your output to see how consistent it is without being regulated? Thanks for all the tutoring.

    Custom barrels

    Hi Chris. Got a text from Tim at Mac1 yesterday. He said he has the extensions in 5 inches and 8 inches. He also explained they come with a collar or coupler to connect them to the stock tube. Then he explained something about fine threads vs. coarse threads that I couldn't get a handle on...

    Custom barrels

    The last time I talked to Tim at Mac 1 he said his machinist was no longer making the air tube extensions. Think I'll go back to see if I can coax one out of him for gun #2. It would allow me to fill without removing the handguard which is a big plus. Does your rig have a meter built into the...

    Custom barrels

    I like it, Chris. Tell me more. What is the extended air tube from? Is it regulated? I didn't realize these guns could handle 1400 psi. How many shots do you get per fill? Do you fill with a high compression compressor? Good work on those laminated grips, they really set the gun off. I've got...

    Custom barrels

    Thanks, Dave. I'm not a sophisticated airgunner, so I never would have made that connection. I thought about going with a Walther barrel for this build since they have a reputation for accuracy. I went with the lower cost option since I didn't know how the build would turn out. What's the saying...

    To answer Weusi2, it's a Crosman 600 semi-automatic pistol that's been modified with an 18" barrel and handguard for use as a carbine. Thanks for your interest.

    Custom barrels

    I want to thank K Moses for politely pointing out that my custom stock was very angular (he called it polygonal). Sometimes we need a little help to do our best and the comment made me think about ways to improve my design. After running through tons of very coarse sand paper I was able to...

    Custom barrels

    They're just a couple of artifacts I picked up when I lived in Montana several years ago. The holster reportedly was owned by Jack Slade, one of the founders of the Pony Express and later a notorious gunfighter who murdered a man for holding up an overland stage. He was hanged by vigilantes in...

    Custom barrels

    Polygonal is a good way to describe it. I don't have an eye for design, but I do know how to make them function. I just resealed my other 600 and will keep form in mind while turning it into a carbine. Am looking at pre-formed hand guards instead of fabricating one from wood. The trick is...

    Custom barrels

    Received my extended barrel and was able to finish the Crosman AR 600 carbine. The barrel arrived .5mm over specs and I had to dress it down with fine grinding stones and sandpaper. After that she slid home and I was able to mate it perfectly to the loading gate. Here is a final photo of the...

    Thanks or the tip, Tim, and glad you like the gun. Will try the JSBs.

    Custom barrels

    Thanks, Tim. I was so pleased when my friend gave this gun to me as it showed very little wear and no signs of molestation. After I swapped out the seals and tuned it up, it fed flawlessly with the stock barrel and RWS wad cutters. It didn't seem to like Crosman premier domed pellets though. I...

    Custom barrels

    Here are photos of something every good soldier needs-a Crosman AR-600. The grips and forearm were fashioned from Canadian rock maple. The receiver and forearm are equipped with picatinny rails that hold a quick-release combat flashlight, a shoulder harness, a Pinty 2.5-10 x 40 scope with...

    Custom barrels

    Emergency averted! My California contact came through and is machining my barrel as I type. Hope to have it in my hands in a week and be able to post photos with a little bragging soon after (if all goes together).

    Custom barrels

    Thanks for all of the advice, guys. I did purchase a barrel from Crosman and sent it to a shop in California, but have only gotten radio silence since, even though he agreed to make me a barrel. Will try to call tomorrow and see if I can nudge them. Meantime, I've contacted the other shops...

    Custom barrels

    Hello all from a newbie to the forum. Am in the process of building a Crosman 600 carbine and am having difficulty finding a reputable source for an extended barrel. Have reached out to one shop in South Carolina and one in California without luck. I'm looking for a standard 24" long 7/16"...
