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
According to Tac-Con one of the touted 3 modes is the safe mode. Every AR made has this mode so I call BS on this.
Take a look at the Hipertouch AR triggers for half the price. I have two 24C's in my 3 gun AR's. Crisp consistant 2# triggers with the lightest springs. They include a set of light, medium and heavy springs as well as trigger and hammer pins. Their hammer is included also.
I haven't tried the Tac-con trigger yet but have investigated it pretty closely. The appeal is simulated fully auto or at least faster then normal semi-auto. How they accomplish this from what I see is to mechanically push the trigger forward so you don't have to by letting off the trigger as normal. It's trigger slap back but a gentle version. If you can get the hang of floating your trigger pressure it will start bump firing. It may be easier to do than with a bump fire stock.
For that kind of money (or a lot less) you can buy a really high quality trigger with a nice light and crisp pull but of course not the novelty.
