I had a little time on my hands today, so I decided to finally swap out the RRA "star" selector in my PWA lower for a standard type selector & I noticed something odd about my trigger spring. It looks like this:



I other words, the spring legs are bent at an angle, which results in a stiffer trigger pull (without the hammer installed) over the normal spring with straight legs.

Now I didn't install the FCG on this lower... I sent it to Accuracy Speaks to have one of their single stage triggers installed, but I did send them the spring kit to use with it & they were just standard Bushmaster FCG springs.

I guess I'm asking if you think that they bent the spring legs for a reason, & what is that reason, or do they use springs that are specific to their triggers. and if so, why a heavier spring?

Thanks.

BTW, Yes, I know... the pic shows two springs.    

Thanks for the insight Tweak.

The funny thing is, I have another lower with an Accuracy Speaks single stage trigger installed, and on that one they used an unbent, standard trigger spring. That one works just fine (no doubling), so I have to wonder... why the bent spring on one, but not the other???  

According to the installation instructions, bending the trigger spring legs as shown in the photo increases the trigger pull weight.  Using the stock spring the trigger pull will be about 3-1/2 pounds or so.  If you need a higher pull for competition, or just want it that way, you can increase it by bending the legs as in the photo.  It's a trial and error process - just keep bending and trying until it is the way you want it.

Thanks twidget. That's the exact info I've been looking for!
