    Little more than a Channel, There is a compound curve cap for the Feed paw arm. Looks better than a squared off box.

    pooks,

    all real PKM receivers are "sheet metal".... if thats what ya mean... but its not a thin or flimsy. they are about as thick as you could ever want.

    Pryotex's receivers are very good & easy to work with.

    YES i was the test builder.. & there were some things i looked for that we can get into if you want more info..

    adjustability, weldability, correct lengths, fits & so on.

    So is that an FFL item or just the shell (hate to call it "80%")??? What must one do to get one? I have a channel for which I've messed around with the bulge for the feed pawl, but that's about as far as I got. Nice to see there are options other than the VLTOR which I was never impressed with... didn't like the machined rail section.

    Non-FFL only so far, It was supplied with 4130 inner rails. (NOT CUT)
    The FFL one is still waiting classification at the Tech branch.

    Pooks,

    not much i can ad to that.. Tony just covered it. :-)

    mine was done as a '80%" non firearm... but things we learned were to not trust ANY existing template out there on the sites.... there are quite a few different manufacturing set ups on these and you need to check your trunny holes very closely to see which ones you have.

    the rest of the stuff was prefect on locations, but since im kinda OCDish... i triple checked all my locations anyway. now that ive done these, it wouldnt be a big deal to do more if i had more kits. this really gets it down to about the level of what we had on early "roll your own" AK building. but shooting these are much more fun.

    Thanks for the update! I'm always interested in BIY stuff of course I created a bulge in my channel but it isn't as pretty. In retrospect perhaps I should have heated the area first to make it softer and easier to stretch. I have some raw materials for the charging handle channel as well as the rails, but I didn't get that far. My plans are to actually buy a house here in COS and set up my garage.

    But if there's a non-receiver w/ precut charging handle brackets etc. that would be useful

    Pookie,


    Yeah Pryotex's receiver has the charging handle slot & the cone on it... so all you have to do is top inner rail install & make your rivet holes and mounts.. then put it all together... pretty easy build this way.

    Very cool - I might be talked into building one before I get my shop "unpacked" Still need to get enough parts unpacked to use my milling machine to machine the slot in that stand-off bar for the trigger. Unfortunately, I have like 40 boxes from my garage, and the idiots that packed them labeled each and every one of them as "tools" LOL

    I found my box of press plates and other parts for bending. I actually bought some large steel bars to fabricate a bending mandrel for the top rails. Since I've only handled a VLTOR I have only had pictures to reference the real deal. Looks like the top of the receiver shell is bent, then top rails installed via spot welds. I need to dig up my reference info as I don't know where I put some of my notes.

    I was going down the path of using thinner springs on both bottom corners of the carrier, then putting a retainer plate on the backside of the carrier for the springs to work against. There is a machining hole on the back of the carrier to which I could attach the plate. There isn't much room there of course but I was thinking a small enough spring (say for example a VZ58 spring) on both sides should have enough force to cycle the action. But all that is going to take time to verify it would function with that configuration and not interfere with the feed pawls. And of course fabrication for the spring retainer plate. It would free up the middle section however and leave plenty of room for a hammer.
