Delrin! Price, quality.
Can't say much here.
All I can say is wow and much more!
F.B.M. Is pure Quality and this trigger is nothing less. What do you get out of this trigger? You get the Speed, the Quality and most comfortable shooting styles.
The trigger is very light which helps in your shooting speed and the trigger pivots smoothly due to it's material, delrin.
I have this trigger for about 3 months, It's by far the best trigger made for a Timmy. 3 Point adjustment for the ultra fine tuning and the smooth style. You can rip insanely fast on these, maybe too fast :)
Did I mention that the trigger comes in two styles? Original ( Bent backward Blade stype) and the Wave, Which is self explantory.
Comes in a nice little box with the F.B.M. logo, can't go wrong on this product!
Best damn trigger out there for Timmies, DM-4s, Angel more.... What can you say about only spending 23 bucks? It's an awesome deal.
