I dont know where he got the mags but this place has standard and extended rd mags for sale. I have not dealt with them so I dont know how reliable they are.
Conversion kit came from Haga Defense but that stick mag from somewhere else. He had to fit it to make it run.
Thanx for the link! I will share with him!!!
BTW: 25 rnd but only likes 20 a load.
I had an older one that stayed in truck box of my Rhino. I finally ended up giving it to my son. It is a compact little package and mine was pretty accurate. It took a little to get used to but overall a really cool survival rifle.
