When I first got this trigger, I was in awe at just how nice it looked. I had a little trouble installing it, but that was because I never opened a proto before. Instillation was easy though, just pop out the stock roller pin, slide in the new trigger, and pop in the new roller pin. I tried walking the trigger without air and noticed that the pull was much smoother and lighter. The first time I played with the trigger I was extremely happy. I had no trouble walking the trigger, it was extremely smooth, and I noticed a slight increase in bps.
My only complaint is that it only came with one bearing. Becasue of this, the trigger wobbles a little from side to side. Other than that, it's a great product.
Conclusion:
Great trigger, not a necessary upgrade but it's a nice little addition to you're gun. I would give it a 10 but because of the lack of an extra bearing, I'm giving it a 9. Great product. NDZ has done it again.
Just out of curiosity, how does this trigger compare to the CP Proto (DM4) trigger? I own a CP roller for my Proto and I dislike it very much. So, I'm seriously thinking about getting a new trigger. Thanks.
