Ok, its been 13 years or so since I owned an AR15(M4 design), and now that I have a new one I'd like to dress it up some. There weren't many options back then, so I'm way out of the loop on things.

Budget is of importance, I'm still not sure my lady friend(she's more than that, no official title) wont beat me to death with this M4 yet for spending the money on my 8th gun in 6 months time. lol

1. I'm looking for a direct replacement for the forearm. One of those quad rail units that all I have to do is compress the slipring & spring down to change it out. Aluminum is preferred over plastic.
2. forward vertical grip
3. green laser w/remote switch
4. flashlight thingy

The factory pistol grip is getting changed out for sure, the one finger groove bump just doesn't work with my hand.

This is the model I have: http://www.stagarms.com/product_info...roducts_id=205

Magazines: From what I'm reading the Magpul's are what many like.. Wheres the cheapest place for those?
