The general way of doing it is to adjust the hammer spring tension for somewhere in the ballpark of 97% of the maximum velocity. https://www.airgunnation.com/threads/regulator-pressure-vs-hammer-spring-tension.1133487

Yes. Pull off stock. Look at hammer adjust screw. Turn in or out to adjust hammer tension. Most have lock nut 🔩 very easy.

I should've clarified op. I know your mind. I micro adjust obsessively. When the ref adjustment doesn't have a gauge to verify. And you cant adjust valve. Hammer spring is the entire ballgame and youre going to have to accept the optivelocity

I weighed the hammer 11.4g and I've turned the adjuster screw in a couple turns but consistency goes down. I'm thinking either the spring is too strong or I need to try a lighter hammer.

I’ve watched videos on the DRS Tactical and they all say the regulator pressure and hammer spring can only be adjusted by removing the stock and chassis. My DRS has an adjustment wheel on the left side precisely where the hammer spring adjustment is located. I went back and looked at videos that...

Thanks so much! I think i will adjust the hammer spring first

Is there a guide that explains all of the above and how it effects velocity and shot count? What exactly the function of a plenum is, how does expanding it change fps and shot count. How does hammer spring adjustment change stuff.

The wheel is coarse adjustment the micro is ultra fine adjustment of hammer spring tension..... The real trickery comes with what reg pressure you're using and the valve adjuster. That's all over the chrono and on target experimentation. Each gun is different enough that a "recipe" is ballpark...

Adjust the reg up, it will go over 30fpe. Sometimes they need a more stout hammer spring as well.

The design appears functional. Of course it will probably need a cut out for loading. What is the bottom of the hammer pocket threaded for? Is that how you intend to adjust valve travel, by stopping the hammer? If so, I would avoid that approach unless some type of damping is involved, like an...

Warnings: Do not adjust the hammer spring if the gun is cocked, or you will be buying a new wheel. You may have to take off that adjustment wheel to get to that hex key adjuster. There are two little ball bearings and two little springs that push on those bearings, to give that wheel tension...

I have been trying to perfect my maverick .22 BT compact to shoot 25 grain pellets but for the life of me can’t get my Allen key to fit into the hole for the adjustment. So… can anyone please recommend what I should set this thing to? Ernest Rowe recommended 6mm in an old video about disassembly...

No. I need to read more. Maybe want to drop the fps in the future but 22gr pellets didnt need any scope adjustments when i zeroed with 14.3gr at 17 yards, both hit same dime hole.

I'm shooting an impact i got from someone. Now has an SD of .8 and an extreme of 3.7fps. 25.39/134/2.125

ok, I'll give it another "shot" (pun intended) in a few days. I'll back down the hammer spring a couple of complete turns. but what am I looking for when increasing and firing a few, (rinse and repeat). Am I watching for the highest vel. achieved using the hammer spring adjustment? Wouldn't the...

My Gen 1 .25 I added the Haji supertune kit. That made the hammer spring adjustable. If i remember drill a hole and the hammer spring was externally adjustable on the G30. Or it already had a hole. 2nd gen .25 and .22 need the supertune kit too.

I have not messed with the hammer spring adjuster, but I will take a look at it. The first shots are kinda loud. It takes several shots before it settles down. I'll probable try a new reg. Thanks for the info guys. 20PPC

There’s a few things I forgot to mention when talking about my M3 I did do an internal polishing of the piston, spring hammer, etc. the hammer I replaced with the smaller Huma hammer but left the original springs. The hammer wheel is at 16 and the micro is adjusted as far to five as it will go...

Or how to adjust the hammer spring on this rifle

Having recently rekindled my half-century love affair with Sheridan pump-rifles by horse-trading for a 70s vintage Blue Streak and a much more recent vintage Sheridan/Benjamin C9A series Silver Streak, thought I'd not only spread a little more Sheridan love (despite there being ample 'round...
