Quality parts with fast shipping and great customer service. Installed in my AB3 hunter in about 10 minutes and went from a 4.25 lb trigger pull to 2 pounds on the nose. Great little kit!

Been looking for trigger upgrade for my Browning AB3 30-06 for several months. Kept looking on web to see if there were any available and spotted MCARBO site, watched video of trigger spring replacement, ordered trigger spring. Being in Australia thought spring arrival would take 3-4 weeks, arrived in under 2 weeks [fast]. Replaced trigger spring made adjustments [30 minutes], result was amazing, trigger pull went from just over 5 pounds to 2.2 pounds, now no waiting for trigger to go off while trying to hold on target, slight pressure is all that is needed. Grouping at the range has improved heaps, GREAT thanks MCARBO. Service was great

Easily got it the AB3 to 2.25 lbs on the Rifle Basis gauge. A big improvement. A tad under 2lb would be nice but I understand there trigger design limitations. I wish it was as good as the Tikka T3 springs I have used..

Spring was easy to install and is definitely lighter. Great product.

I rate the ab3 trigger spring highly the trigger weight went from around the 4.5lbs to 2.5lbs feels like a new gun now 50% reduction is on the money keen to get out in the field. Thank you Mcarbo great company to deal with only took 5 days to my door in Australia as the estimated delivery time stated great costumer service with the follow up emails. Shoot straight guys cheers
