M*CARBO Brotherhood

Win 70 M*Carbo trigger spring - what an upgrade!

Ordered my M*Carbo pre 2008 WIN 70 trigger spring upgrade on Wednesday, received it on Friday, installed it on Sunday and shot on Monday… all I can say is WOW. One of, it not the best, upgrade I have ever made to a rifle. Trigger pull came in at 2lbs and the install was super easy with the youtube video… can’t believe how much difference a spring could make, my '06 is dialed in and ready for elk season. EXTREMELY satisfied! If you’re thinking about this upgrade, go ahead and pull the trigger on it (no pun intended), you won’t be disappointed.


Welcome aboard! I’m sure your find the same results across their whole product line.
I run their springs in my AR15, AR9, FNS9, Moss 500, AK, RS22, AR mags and have zero complaints or issues. I’m sure there’s other who can vouch for other upgrades available and describe their experiences.
Have a look around here, you’ll like what you find. Rest of us seemed to.


Roger that, filling the shopping cart up all ready-haha
