## Customer Reviews

### ⭐⭐⭐⭐⭐ excellent option for 2240 pistols.
*by M***Y on 10 June 2025*

These work great on my Crosman 2240 pistol to allow me to mount a scope or red dot sight using the standard plastic breech. The choice of sights with 11mm mounts are quite limited in my experience, but they are out there.

### ⭐⭐⭐⭐⭐ Site rail holder for Crosman 2400 CO2 air pistol
*by K***1 on 17 September 2023*

Only method I could find to fit this air pistol. Easy to fit and use , value for money piece of equipment .Excellent !

### ⭐⭐⭐⭐ Well Made And A Good Fit
*by J***R on 2 March 2024*

I used these to fit a red dot scope to my 2240. After a couple of target sessions and zeroing in the scope it all feels rock solid and is shooting tight groups consistently. If there is any loosening of the mounts over time I'd recommend using a thread locker like Loctite 242 to keep everything in place. Remember you are clamping directly onto the barrel so vibration will be an issue.
