PSA is having a monster sale. Only thing that sucks is that internet sale prices are not honored in store. However, you can build an AR with all PSA stuff (and their barrels are made by FN unless otherwise noted) for right at $500 that is just as good as any $1000 off the shelf unit.
That link there is a great deal for a trigger group and lower parts kit. Site shows out of stock, but they have them in the Columbia store......I just bought the trigger today. Trigger without the lpk is $65, and they had one installed on a range gun and were kind enough to let me dry fire it. That thing is like butter after using a standard trigger group. If you want anything that went on sale today, better get it now cause it will run out,
