    Default AK-47 BELTFEED PROJECT

    HC.

    You know even thought is does appear to have a fair amount of recoil, it makes it that much more fun to shoot. More like a more powerful MG than a something that shoots the small 7.62x39 cartridge. That's one reason why I built it, that big gun feel with out the higher cost of 7.62x51 or 8mm ammo plus to see if I could really make a beltfeed out of AK parts.

    Next project, is make a beltfeed FAL. And yes, the receiver side rails will have to be reinforced but when you start with a rough casting I can modify it as required to make it strong enough. As a Mechanical engineer, I can and will calculate the receiver side rail stresses and beef it up as required.

    Thats an awesome build. I am a little puzzled about the recoil though. Would it lessen the recoil if You moved the vent hole on the gas tube forward a little to bleed off pressure at the rear of the piston stroke so that the carrier isn't slamming into the buffer as hard? I've never even looked at belt fed so I don't know what all is involed, but it seems logical? Maybe???

    You are probably right. Right now the gas bleed off hole is right at the rear most travel of the bolt carrier. My 300WSM FAL has multipule gas relief holes in the gas tube and a sleeve that I can slide fore and aft to cover and uncover the holes. I think I will try your suggestion and do the same thing.
    The other thing I think I will do is drill and tap a hole in the gas block that intersects the gas port. I can then put in a tapered screw and adjust the gas port hole area. You can buy a similar gas regulator block system for a Mini-14.

    What is the inside width of your tubing? 1 1/2 x 1 1/2 x .12 wall should fit. However, structrual tubing is no thiner than .12 but can be thicker per tubing ASME thickness specifications. I believe I had to very slightly machine the inside of my tubing a small amount to get the trunion to fit. It was only about .010 per side though.

    Great build. Btw, do you need anybody to clean the inside of your gun safe? *wink*

    No but really, its is awesome. Next time it would be cool to have a belt/magazine fed. Similar to the 249, but in 7.62. Two thumbs up. Next write the tutorial

    Freedom is not free. Some will perish to preserve it for the many. Just as our Forefathers did before us, we must take up the battle and not waver. Victory is our only option.

    This weekend, if I get done helping the wife paint my son's room (yuck I hate painting!), I plan to go out to the desert and make a video of it shooting which I will post.
