Hello all

[Rockwolf66]

Factory mags are only 3 rounds? I thought it was five. Hmm.

Well that's how many .300 Winmag rounds fit in a Remington Factory detachable magazine. If I was fireing .308s I could fit five of them in the same space.

as for my friend's HK-21E it tends to be ammo sensitive. as for his G-3A3 and MP-5 I have heard no complaints about them. Trust me the MP-5 is a sweet setup, just look in Armed America and see for yourself.
