PCP Beeman Regulated Commodore UnderLever

[Don.S]

Just purchased a Beeman Regulated Commodore Underlever in .177, The manual does not mention regulator adjustment and I trying to find a way to adjust the regulator to tune the gun. When searching for regulator adjustment all I come up with is installation of a regulator. The manual only mentions hammer / spring power adjustment.

Thanks, in advance for any info.

Although I am not familiar with this model in detail, it is possible that the regulator is non-adjustable. At least not without disassembling the Belville washer stack and reassembling. And I would definitely NOT advise that!

One suggestion would be to contact Beeman directly and ask for advice.

However I have to ask why you want to adjust the regulator? It could be that hammer spring tension adjustment may provide the results you want. What sort of tune are you looking to achieve - more power, more shots per fill, or what?

Hi. I'm looking to get more shots out of it. One 10 shot group of 8.1 GR HP came out to 900 FPS and 14 ft lbs. Avg was 905 with a std dev of 3.38. I've got a message into the vendor I bought it from and Beeman. Been too hot to do a max string, but I'll try to today before sunset. As I understand I can tune by lowering the regulator first, then adjusting the hammer spring so the std. dev. is at a minimal. Thanks, I'm just looking to learn tuning, and pass the time with the rifle.

Hammer spring adjustment should enable higher shot count and lower velocity. Next should be changing to a lighter spring.

An SSG device would be an effective way to increase shot count.

Simple things first. Especially if the regulator is not externally adjustable.

Thanks for the reply. I'll be researching the SSG device a little more, it's my first rodeo, and I understand it to be a way of preventing hammer bounce.
