Overall Customer Rating of 51 Reviews:

Highly recommended

Major improvement! I don’t have a trigger pull gauge, but the trigger is dramatically lighter and more crisp now. The parts arrived very quickly and were easy to install. Detailed instructions are available on the website, but I’d recommend watching the installation video.


honest detailed review

where to begin.. installation was super easy and took around 10 minutes. i like the allen set screw way better than the factory Phillips. it allows alot more adjustment and the ability to completely eliminate the first stage of the trigger to greatly reduce the pull. im disappointed the pro kit no longer comes with the 3 new stock screws as the factory are basically trash.. the reason i only gave 3 stars is the fact it didnt reduce my pull near as much as advertised. i went from a 7.1 lb pull to a 3.7 pull. i really would like a sub 2 lb like advertised but no such luck. the washers are nice but i could only fit one not the two.. i wish i had experience with other kits so i could give a comparison but ive only had this kit so far.

I just purchased a Benjamin Vaporizer .22 caliber air gun. This gun is made in China. The gun shoots 1 inch groups at 20 yards. I used a RCBS trigger gauge and the trigger pull on this gun was awful at 8lbs. I installed the MCARBO Pro spring kit on this gun as instructed. The install was easy and only takes about 15 minutes. I could only use one shim on this trigger to take up side slack. While the kit took out the trigger pull slack it only took the pull weight down to 5.75 lbs. Trigger is smooth with no grind. I was a disappointed in pull weight reduction as I was hoping for 3lbs or less. Kit is still a good install for the gun.


Benjamin Trail Stealth, spring kit

Found Mcarbo in a few reviews on how to make Benjamin triggers better. I ordered 2. Took about 15 minutes to install and reassemble the rifle. This kit is a MUST Have. Trigger pull went from 6 lb to maybe 2 lb. All you need is a tube of blue lock Tite for screws.
Thanks for your great kit.

Crosman Valiant works okay

M*CARBO shoots straight so I will, too. I’m torn between a 3-star and 5-star rating so I’m giving it 4 stars.

For my Crosman Valiant I could have gone with the basic kit and saved myself a little money. For example, the trigger didn’t really have much wobble to begin with, and using both shims made the trigger tight in the housing. 1 shim is all I needed (and didn’t really need even that). Also, the original trigger adjustment screw that came with the air gun provided me enough adjustment so I didn’t really need the Allen screw provided, so I honestly would have been fine with just the main trigger spring replaced. Thus, I’d have gone with a 3-star rating simply because the description and advertising made me feel like I really needed the whole kit when I didn’t.

However, I’d have given it 5 stars because if I had different airgun it’s possible I’d need the whole Pro kit and it’s VERY well made, with clear and easy to follow video instruction, and made a BIG difference in the reduction of trigger pull weight.

Also, their customer service is absolutely fantastic, thus it could easily be 5 stars for the rating.

I’ll land it in the middle with 4. Either way you can’t go wrong with this company. They’re solid. They’re 100% USA, love and support our Constitution (yes, especially the 2nd Amendment), support our troops and first responders, and genuinely want to make quality products that help people.
