    Default Conversion help.........AM I nuts?

    I want to convert my CAI angle cut reciever MAADI to an underfolder. I have an underfolder with trunion coming. What am I looking at as far as work....not that I mind...I love the work, but I want to be sure what I'm doing.

    Can I cut the holes for the underfolder in my reciever?
    What rivets do I need to secure the rear trunion in the reciever?
    Help me out....... has someone attempted this before?

    What tools will I need?

    I really want an underfolder and the angle cut reciever is just begging to be used.


    Please don't tell me to sell the MAADI and buy an underfolder.....I want to do the conversion.

    Thanks

    Conversions can be difficult, so keep in mind you may have to ?reverse engineer? something.

    I say go for it. You have to keep the manufacturer markings, importer markings, serial number, etc. intact on the receiver. If this were a Saiga, you would simply take a stamp set of the proper size & stamp the info at another location on the rec to the appropriate depth. The stamp info is covered in other subjects, so use the search feature to dig up that info if you need to do it.

    I?m not familiar with the Maadi. If the buttstock is a US-built part, you should get another part to replace the US part you?ll lose when converting. Assuming this rifle falls under the 922 parts-count quota nonsense.

    Slant-cut receivers. I can say that any receiver can be cut to use the stock mounting frames (aka tang or rear trunion). It is best to hand-fit the frame to the receiver and then mark the holes, drill and rivet. McMaster-Carr 5/32? rivets will work perfectly.

    This was originally a butthole stocked Century import. This particular MAADI is a bastard case. CAI used MAADI recievers and MAK 90 parts to put this one together.
    Here's a pic:


    CAI angle cut the reciever and put a MAK 90 style butthole on it to try and prevent conversion to a regular AK stock set. It has a regular rear tang, and had a 1/4" plate welded to close the back of the reciever. I cut out this plate originally and fitted a regular stock to it. It's not the greatest fit, but the look is good. All other 922 mods were made as well; i.e. gas piston, trigger group, pistol grip..... it currently has 5 US parts. The stock currently on it is not a US part.

    Markings should not be a problem as there are none in the area where the underfolder holes would be.

    What tools will I need to install the trunion? Bolt cutter riveter? Rivet jig?

    Never really looked at an underfolder that closely....just my unfamiliarity with it.

    Yeah the bolt cutter riveter should fit - I ground a 2nd set to make it fit all the way into my Yugo build and it workd fine. The long rivet can be hammered in the normal fashion.
