PROBLEMS SO FAR

Post by SHARPSSHOOTER5090 »

IT FEEDS AND CHAMBER THE STANDARD 7.63X39 AK-47/SKS ROUND BUT I NEED TO FIT A STRONGER BOLT CARRIER RETURN SPRING. IT HANGS UP ON FEED SOMETIMES. I HAVEN'T GOT THE FIRING PIN MADE YET SO I HAVENT SHOT IT YET. I HAVE 2 DIFFERENT TYPE OF BELTS, A STANDARD MG34/42/53/3 8MM/308 THAT HOLD THE 7.62X39 CARTRIDGE NICELY BUT NOT TO LOOSE. I ALSO HAVE A RPD BELT FOR 7.62X39 BUT IT HOLDS THE CARTRIDGES VERY TIGHTLY. I DISTANCE BETWEEN CARTRIDGE TO CARTRIDGE ON THE RPD BELT IS CLOSER THAN THE DISTANCE ON THE MG BELT AND SINCE I AM USING A MG BELTFEED ASSY, I HAVEN'T YET TRIED THE RPD BELT. IT MAY NOT ADVACE THE CARTRIDGES CORRECTLY. WILL KEEP YOU ALL POSTED AS I CONTINUE TO MAKE PROGRESS. AFTER I GET IT TO WORK RELIABLY, THEN I WILL CONCENTRATE ON THE FINISH.

Feed pawl to feed tray distance

Post by SHARPSSHOOTER5090 »

Can anyone tell me the vertical distance between the tip of the feed pawls to the feed tray surface where the cartridge/belts slide please? I may have to much distanced so the feed pawls bearly catch the top of the cartridge so I don't get reliable advance of the cartridge/belt.

How much does it weigh? Have you thought about the strength of that gas tube as a hand hold? Are you planning to beef it up and create a new handguard? I know it's just an experiment and you might not be thinking about these details yet.

The front end is starting to mimic the RPD a little. Did you think about the RPD feed top cover?

It is an interesting combination though of readily available, cheap kit parts - ak, M53.

I wonder how many hours you have already worked on it?

Scratch Built Receiver

Post by SHARPSSHOOTER5090 »

I started out thinking I would use AK and rpd parts but the cost and availabilty of mg parts steered me toward the Ak and mg parts.
I am planning to replace the AK gas tube with a non-fluted tube and caping off the gas relieve holes in the AK gas block in order to convert the gas piston from a short impulse system to a long impulse system. I am sure I am going to need a lot longer push from the gas piston to move the heaver bolt and to overcome the extra force required to operate the feed cam. The AK handguards are there for the pictures only, they will also be replaced with somethink more robust.

That is even cooler than the AK-Bren concept I was thinking of a while back. (Thinking of. Never made it past the thinking stage. I just dont have access to a machine shop. Looks cool though, kinda like a M60 and Ak morphed together.
