As an introvert by nature I wouldn't ordinarily post information unless it was advise requested of me. As an airgunner wanting to be able to fully use this site, I find myself posting more than my personality would like. That said, I didn't see much on the Buck Rail moderators for Crosman 1377 and thought I would share my impressions.
First, I have no affiliation with this or any company. The customer service was great. Although I never spoke to anyone, his site was easy to use and he shipped my purchase out the day after I bought it with easy to track shipping info. I found the moderator easy to install and I was very please with the results. I should say I purchase three moderators that day, one 1/2" universal, one for a Crosman R1, and the one for my 1377 (heck they ae pretty inexpensive). I tried the R1 first and it did not make a big difference, but that gun is pretty quiet to start with. I was concerned that the others would have similar results, but to my surprise the 1377 was a night and day difference at 10 pumps. I tried the universal one on my Seneca Dragonfly Mk2 and again on 15 pumps it is extremely quiet. I used to be concerned about "alerting" the neighbors, but with these installed, I can shoot all day with no concerns. Pic of my 1377 included.
