Winchester 70 trigger spring kit

Was hoping to reduce trigger pull weight down to 1.5 lbs instead of 3.5 lbs. with this spring kit. With new spring, pull weight is still 3.5 lbs. MCarbo is great, fast shipping, received product within one week of placing order, great communication from MCarbo as to order/shipping status. Installation video(Youtube) was easy to follow, 10 minute process. Thanks MCarbo, I give you a 5 star rating, just wish the spring would have reduced the trigger pull weight.

BE AWARE !!! Purchased 2 Win 70 post 64 springs. One gun a 375 H&H, other 270 Win. Professional gunsmith called. He said as per his practice after trigger work. "After installing to 3-4# TP, he tapped the 375 on the floor. trigger fired on 3rd. tap, multiple times. 270 trigger fired on 4th time tapped on floor. Tested many times." I will share gunsmith name and number to the owner of M.Carbo Can't believe I'm the only one. All buyers, try the simple tap on the floor, Just trying to prevent an accident. DBL GNR

Performed as advertised

Purchase one MCARBO spring kit for a pre-2008 Winchester M-70 Stainless Classic. Replaced the spring in less than 5 minutes as claimed in the add. The result was a trigger pull less than half of the factory spring. Was so impressed I bought two more for my other Model 70s. I would definitely recommend MCARBO to my friends who own a Winchester Model 70.


If you own a model 70 this is a must have very easy to change out if you watch the video took about 10 minutes and the results are unbelievable took a 5.4 average pull to a clean 1.9 fast shipping to boot what’s not to like. Thank you for a great product and thank you for your service to our country!!!
