It worked on the carbs for my F3. Biggest thing is to make sure you get it dry and oiled to avoid rust

 

Yes, it's a detachable Tapco composite mag. Some of the steel ones do not detach. Tapco 20rnd mags are the best I've had as far as function and fit... and they're only about $18. I've used stripper clips a lot, though, and I'm probably quicker with them but the capacity is less for a good "go" at a target.
Just remember, though, unless your SKS has 10 or less imported parts.... it's not 922R compliant. You can't just use detach mags and be legal. You need to use all original equipment to comply with the b.a.t.f..... or you have to have 10 or less imported parts off the compliance parts list in total.

Mine has the original mag on it right now.

And kuro... can't you just remove the firing pin, clean the pin and carrier, and put her back together?

 

It's not a 'user serviceable' item. Meaning, of course I can find out how to remove the pin myself. And void the warranty

 

Ive got a Glock 23 and 27 as well, MUCH rather carry the 23, i just feel more comfortable with it. Still not as accurate with the 27 yet, but im sure its just as capable.

 

hahaha this made my day
