SKS AR magwell conversions

Maximum capacity is based on origional intended firearm magazine is for. Regardless what gun it's used in.
Aka 10 round pistol mags are okay in rifles if they were made as pistol mags. However if it's made as a rifle mag 5 is max.
I've just finished installing my XCR mag adaptor from HICAL, and I'm pretty happy with it. Haven't fired it yet (tomorrow) but it feeds dummy rounds flawlessly.
I wouldn't consider it a DIY project unless you have a milling machine.
Forward end of mag well after milling (used a 3/8 carbide end mill) , you can also see what the bottom of the breech block (bolt ?) looks like after milling .....
Aft end of the mag well .... you see where I deepened the 'Hold open device' about 1/8" ( again with 3/8 carbide end mill)
Picture of unmodified HOD for clarity (pic stolen from the internets)
Three angles of the breech block (bolt?) after milling with 1/2" carbide end mill .....
Unmodified bolt for comparison ......
After all the metalwork was done, about 15 minutes with a chisel opened up the inleting of the stock and that was it.
There are no published dimensions for the machine work so it was whittle a bit at a time and test for fit.
I also had to modify the mag slightly at the front and rear for bolt clearance. I suppose I could have cut some material off the bottom of the bolt
but it was just easier to take a file to the mag .....

Went to the range this weekend, attending the EOSC Fall Milsurp shooting match. Great fun!
Just for the fun of it, I decided to use my modified SKS for the "Mad Minute", thought it'd be a great test for it (even if that put me out of this short competition, ranking is reserved for "as issued" firearms
)
Flawless operation, I went through 50 rounds. here's the video; skip to 2:20 to get to the actual mad minute. I'm about in the middle of the pack, and the only one with a plastic stock of course... Next to me was a Mosin M44, great fire breather. Near the end, I'm emptying a mag in about 4 seconds.
All in all, very happy with this project.

bought this recently off a great fellow nutter, he did the work for the adapter and polished the steel to a chrome finish and I'm the proud new owner.
