An excellent choice for a trigger group upgrade

by -

First of all, kudos to Primary Arms for their fast order fulfillment and shipping! This is a fantastic upgrade and marked improvement from an OEM mil-spec trigger. Smooth and crisp in all aspects with a solid tactile reset. Machining, fit and finish are top notch. A definite improvement that has enhanced my shooting accuracy. Installation was easy and straight forward, just drop out the old and drop this in. I can definitely recommend as an upgrade!

A little bit more of an edge


Very nice trigger I have one in my hbar 10 and my hbar 15 , I know the instant my guns are going to go off . I love them for long rang shooting !

Better than RR and just as good as Geissele


Honestly this trigger is still under the radar and you have to feel this to believe it. Best 2 stage trigger and they could charge twice as much and I would buy it. Milspec strength springs is just the cheery on top. Drop in are easy and neat but this trigger will change your life

A must try

I had to try this trigger for the value of it. 2 stage nib x for under $100. This trigger is amazing. Very well built trigger, clean break, crispy. I agree with other reviews here, this trigger is underrated. I bought 2 more when they went on sale. With the price and value of it, you have to at least try it. You have nothing to lose.
