CMMG upper- JP trigger

[inter1]

Hi.I am thinking of buying a CMMG Sierra 22 LR upper to go with my self assembled Olympic lower fitted with a JP trigger.I have read that could turn into an unreliable set up because of the JP spring being lighter than a stock spring will give lighter strikes.I only read this once in a posting  ,anyone as any idea if this set up would work or not ?

Thanks for any suggestions.

I have not heard that before. Is your trigger running the reduced power springs? If there is an issue you can spend $10 on a JP alternative spring set

Hi. Thanks for the reply.I build this lower over 10 years ago, just do not remember ,but i am allmost sure it is just a standard trigger.I just have to try and find out.This rifle as not seen daylight in many years,I have a C&R licence and all my shooting was with bolt action military guns.
