Phase 2? Reactor valve?

[dawsonsigep]

I recently flipped through the latest edition of APG and came across one of the many mail order ads. Within the ad it had upgrades for the mag. I was wondeing what the "phase 2" is. I know it replaces the back end of the mag reciever but what does it do? Also, what is the reactor valve? It replaces the on off valve and other than that I have no idea what it does. Are these upgrades approved by AGD?:confused:

Basicly all they do is lighten your wallet... And NO they are not approved by AGD. So basicly they take your money you could have used for other stuff , and void your warrantee...

yeah they are pointless upgrades, stick with the AGD parts, they are guarenteed to work with your mag better than those aftermarket parts
