definately try one of the site supporters first i always prefer to buy local. If you still cannot find what you want try bravo company or pk fireams i buy quite a bit from both. edit: i bought a prs for $200 new on gunbroker (during the obama scare even)Which Magpul stock are you thinking of, the ACS? I've got the CTR and it is a top notch stock. I'd expect the same out of the ACS.
A good place to start for accessories is the site supporters. There are several top notch companies that are members here and also advertise here on INGO.
I've personally had very good success with Indiana Supply Depot, run by member CWood.
local is always best... that being said ... if you like green check out DSG Arms: and look for the going green sale. I picked up a UBR for $200 in OD greenanybody got any feed back on the new magpul stocks ? where is a good place to find good prices on ar acessories on lin besides cheaper or sportsman guide thanks looking for drop in triggers and furniture,chrome bolt ,quad rail thanks
