The sounds I hear now are the hammer/spring and the pellet splat, that's it! This kit is amazing! The adapter fit perfectly, the suppressor screwed on to the adapter easily and securely. Now my Crosman 1322 is a (nearly) silent target and pesting tool. Customer service is awesome and very helpful! Thank You Buck Rail and crew for a great product! I'll be back soon for another kit for my 1377!!

What an amazing company. Outstanding customer service. Everything work as described. My Crosman 1322 looks awesome. Thank you Terry

I Bought the 1377 suppressor kit and it is amazing. It arrived fast and works great. Always good to see a family owned business catering to the people, who sells excellent products and cares. Thank you so very much.

My brand new Crosman 1377BR pistol had an issue - the barrel band had too much play in it, permitting the barrel to torque to the left. Although I could straighten it, I needed a permanent solution. From reviews online I determined that there is quite a bit of variability in the barrel bands from Crosman and that they are made of a soft plastic, so I saw no reason to send the pistol in for warranty service. Instead, I applied the shipping charges to the purchase of an aftermarket replacement barrel band. I wanted something reasonably priced that was made of stiffer material and that also had set screws to hold the barrel firmly in place. This adapter from Buck Rail fit my requirements and fit my gun perfectly. The only issue I encountered is that the Allen Wrench sent with the adapter for tightening the set screws stripped out quickly, so beware of this potential issue.

I'm giving this five stars. Seldom does anything actually do what it supposed to without embellishment. The common issue of front sight elevation using a steel breech, LPA rear sight being maxed out, raised it's ugly head and didn't work out for me with that gun. Luckily I had a factory packaged 1377c to set free and the factory breech and rear peep work fine. I would like a taller blade option to use aftermarket sights and steel beach without extending the barrel. That being said, the thing is so quiet, the pellet hitting the target is louder than when the gun goes off. The modular superior is cool as well, it only needs one or two chambers for nearly silent shooting. Keeps it Short too. All my emails and concerns were addressed. Very much appreciated!

3 out of 4 adapters installed perfectly. Fourth adapter had one misaligned hole on the exit side of roll pin that was not noticed until pin had been re-installed and it broke the adapter flange on that side. Will have to order another adapter.

Best ever - I now have silencers for my 3 crosmans...very happy, great customer service and great email response time! Go TX!!!!

This kit is excellent. The suppressor works just as well as the one my son-in-law paid $85 for, so $25 is a steal. The company's customer service is 2nd to none!

Fits great, looks great, substantial noise reduction. The hammer spring is louder than the muzzle noise. Will buy another for my avenger.

Bought kit to replace a kit from another company that broke at the thread base. This kit was made much better as the threads were larger and gave the adapter more strength when threading and unthreading suppressor. Really quiet when shooting (9 pumps) and accuracy is good to.
