I recently received a new Beeman AR2078B. It's a great fun rifle for ten meter shooting. I'd like to reduce the velocity to make it quieter and get more shots per fill. Right now it is getting 635fps with an 8 grain wadcutter and its giving just over 40 shots on a single CO2 cartridge before I see a slight drop in impact on the target. My goal would be to reduce the velocity down to the 550-575 fps range. I believe that would make it a bit more quiet (not that it is super loud ) and offer up a few more shots per fill.
My plan is to slowly clip coils on the hammer spring and see what that gets me. I have also read where people have tried to shed a little weight from the hammer itself. I will try the spring first. I can purchase the whole hammer kit from Archer Airguns so I have a back-up plan in case I mess anything up. I think if I take it slowly and use my chronograph I can slow walk it into the velocity range I'm looking for.
I'd like to run this plan by everyone here just in case I'm overlooking something important. This is my first QB/AR78 style rifle but I have confidently worked on my FX air rifles internals as well as a couple Marauders. Thanks for reading,
Kenny
