I tested the rifle the other day by fitting a hand-operated
valve, to test the breech seal and bolt cycling. Everything is working well and in this setup the gun penetrates 450 pages in the phone book test, and recoil is similar to a .22LR. When completed the gun will be even more powerful even in automatic fire.  | ||||

Here is an update:
I've had plenty more time to continue working on the gun, and now the barrel has been threaded and screwed in (detachable, and locks firmly into gun) and I've machined various internal parts that can't be seen. When complete, the barrel will be floating inside a hollow handgrip for extra accuracy - nothing will touch it in front of the chamber thread. The calibre is .22, and I've built the feeding port to take anything from round ball to 28 grain eun jins.  Close up of breech.  Barrel attached | ||||

Thanks. The barrel screws into the front - the picture
below makes it clearer. The bolt (carrier) seen is the part that will cycle on firing, like in a real rifle. I feel very fortunate to be able to build what I've designed. Otherwise I'd be paying someone else to. Careful with those fingers! | ||||

The threaded hole visible in the photo, is that where the barrel goes? Looks very well done!! I have some CAD prints that I made up a while back...I really wish I had free use of a machine shop
 I take it the bolt is in the photo as well; right? It all looks really good-professional. I am almost finished with my gun, had to use aluminum U channel instead of the stainless due to ease of manipulating it; small parts got very hard to cut..., not my finger though. Oh well, it will heal. | ||||

This is one of the guns I'm working on - 5.56mm / .22
pellet auto. The lower receiver so far is over 1Kg and the gun will be quite hefty when complete and full of gas. | ||||
