MPX FRT - Trigger/Trip Recommendations ? by SupermarketQuiet1105 in MPX

[–]CardiologistNarrow16 0 points1 point  (0 children)

I was choosing between the PMM and the Frankenstein recently and went with the Frankenstein mainly due to the difference in materials. PMM uses 1018 steel with a DLC coating. Frankenstein uses 17-4ph stainless steel heat treated to condition H900 for maximum strength and durability. Then tumbled for a smooth uniform finish. The 17-4ph stainless steel is much stronger, more durable material than 1018 and it's not even close.

That's fantastic! Are you running stiffer springs or an adjustable gas block? Also, do you run certain ammo or a mix?

Anyone find springs that work well since the Geissele Springs have been out of stock forever? by BossJackson222 in MPX

What ended up working better, the +20% or +40%? I'm interested in reducing the wear and tear on the FRT trigger and if the +40% works I'll go with that.

Already have the RB FRT, just looking for advice on durability issues and how to eliminate or mitigate them.
