dr.beav: May be this is off your topic but what I did was replaced my standard springs in my AR-15 with the following: MidwayUSA product no. 579878 JP Enterprises Trigger Spring kit AR-15 3 1/2 lb. Reduced Power; (price $10.49). Originally I bought the standard STAG Arms complete lower kit (what I read was highly recommended as they do some work on the hammer & disconnector) and just substituted the 2 springs. No creep, crisp pull and cheap (single stage trigger). Say you bought the springs and really loved them, then you're $440.00 ahead which will help with your trapshooting. Also, feel free to ignore my post. Good luck with whichever route you go. BT100dc
