Dirty Bird Industries AR-15 Trigger Reduced Power Spring Set
Dirty Bird Industries is excited to announce their new Dirty Bird Industries AR-15 Trigger Reduced Power Spring Set! Mil-Spec triggers have been used for decades, but have always suffered from an incredibly heavy trigger pull weight, that can be upwards of 7-8lbs. When installed, the Dirty Bird Industries AR-15 Trigger Reduced Power Spring Set is capable of producing a consistent 4.0-4.5 lb trigger pull.
The DBI Reduced Power Spring Set have been designed to work with single-stage triggers and will not work with two-stage triggers.

I never thought an inexpensive enhanced mil-spec trigger could be so damn good.....
Wow. Totally impressed with this trigger. I come from 8 other AR's with upgraded triggers, some with triggers that cost in excess of $250. This trigger really does give them a run for their money. The bearing surfaces on this trigger have all been ground nicely, and polished. It comes with a dirty bird reduced power spring kit (includes; trigger spring, dis-connector spring, and hammer spring) works really well. I'd say I'm probably right about 4.0 lbs. For the bargain price I paid, this product totally exceeded my expectations! Highly Recommend!
USUnbeatable Mil-Spec trigger
Trigger has the main areas polished and the reduced spring kit is great. If you need a decent trigger until you upgrade this is it. As always great shipping time.
USFantastic
I was totally impressed with this trigger group and reduced power springs. I put them in a PSA lower which had a milspec trigger which was really bad, heavy pull, grit etc. This set made the trigger lighter and no creep and solid pull no grit or creep. I would highly recommend it if you don't want to drop 100 or more on a drop in.

Great value for a low price.
USNBS Enhanced Fire Control Group
Worked great! Was able to install it with no issue and loved how it didn't feel cheap. Range tested, and isn't rough. Def would recommend for a budget trigger!
