Solid, easy, excellent trigger

by -

I purchased this earlier in the year and just now had the chance to install it in my Aero lower. The parts were in one single bag - but anyone with a brain can determine which springs are which.
<br>The parts were sized perfectly - no sanding or machining to get them to fit. The ambi safety is a nice touch as I shoot left handed. I would say that the long arm gets in the way but it's just something to get used to.
<br>The trigger - wow. Nice and crisp. Way better break than my Tom's Tactical 2 stage and my PSA NB.
<br>This kit is about twice as much as other kits but I'd totally buy it again.

Disappointing.

For the price, I’m very disappointed. Kit came jumbled together and unorganized in a plastic bag. Lower parts kits for a fraction of this at least come organized so you don’t have to dig through everything to find the right spring.
<br>The worst part, however, were the roll pins for the trigger guard and bolt release. They were grossly oversized. It would take you a bottle of oil, channel locks, a heavy hammer, and an hour of your time just to get one of them half way in. You’ll probably end up doing a number on the finish of your receiver as well. I literally had to punch the pins out of another build just to assemble the rifle. Should have just returned the whole kit and bought something else.
