.22 Parts Gun

[Quiet-Matt]

.22lr trainer/kids gun. This one is the king of parts guns. I assembled it for next to nothing using mostly parts I already had, some items from the garage and a trashed barrel. Yep, the barrel literally came from the trash can. A friend had received several parts as part of a trade, and in the mix was an old barrel that looked to have been pieced together with a rock. The sight tower was not even close to being aligned and was barely held on by roll pins that were bent and driven in about half way. It had a dinged up three prong flash hider that had no washer. Best of all was the barrel extension that was screwed on hand tight and had no indexing pin. Once I realized that the barrel had potential as a rim fire barrel, I retrieved it from the can and got to work. I re-aligned the front sight with the existing holes and installed new straight pins after de-burring the holes. I made the end plate attachment point by welding a loop from a cable clamp onto the end plate. The hand guard cap is kept from rotating by a roll pin that replaced the gas tube. As for the barrel extension, I re-tourqued it and drilled it for a new index pin. You can see in the picture below that the feed ramps are off by about 90deg since this was apparently not the original for this barrel, but this isn't an issue with the .22lr chamber adaptor. Since the .22 conversion bolt doesn’t require a buffer, I made a plastic plug with a section of tire iron in-between for the receiver extension. I removed the prongs from the old flash hider and made it into a thread protector. Behind that I wrapped aluminum tape to a thickness of 0.865", same as the flash hider, to allow mounting of a bayonet if desired.

That is some good work. It goes to show what a little creative thinking can accomplish.

I like it. In fact, I like it a lot! Using all the trashed stuff to make a working toy is very cool.

Very nicely done.
