Forgive me if somebody has already posted this (not enough time to go through all the posts) but that appears to be a 7.62x39 PKM you are building.

Your build also reminds me of the M-60 with ejection port cut on the side (opposite side though) and the long channel for a receiver.

The PKM is an upside down, belt-fed AK47 in 7.62x54R. I have a kit and an 80% receiver that I have to build.

VERY cool my man...

thanks,
Ron

What just occured to me is that I haven't shown the adjustabe gas relief tube on the gas tube I have planed. The pictures of the gas tube have only one gas relief port one each side. I think I will try it with just the 2 holes and if it throws the bolt back to hard I will drill 2 more holes about a half inch forward of the exsisting ones.

Hey; I never felt for myself when shooting my AK; but will the handguards on the gastube get hotter then the ones on the barrel? I do not know if the heat generated by the gas in the tube is greater than the heat generated by the friction of the bullet in the barrel.

On my FAL the barrel gets much hotter quicker than the gas tube but the gas relief holes are only about 1/2" back from the gas block. I am sure I will have to put a heat shield in the lower handguard to protect it from direct contact from the gas that comes out of the gas relief holes. For now, I will try it with out any lower hand guard until I am satisfied with the functioning then I will add all the bells and whisles and finish. Now if the weather here would just stay dry enough so I can go out to the desert and try it. I don't believe the local gun range will look favorably at any thing that looks like a machine gun, even though it is SA.
