Any Regulated Bullboss Rifles Out There?

Ive regulated 4 different Bullboss and AT44's. Ive used the Lane regulator. Mostly becouse its very easy to get and with the exchange rate it's been very good priced. Its very easy to order on laneregulator.com pick your gun and fill out the questionnaire, Pay with PayPal. In 8 days your regulator show's up in your mail box. It's fast, easy and fair priced.

If the Bullboss/AT44 is rock stock .25 setting your regulator at 125bar you'll see 28 shots at 780fps with JSB25gr pelletsfrom a 200 bar fill. Right now on the stock bullboss/AT44 your with the bell curve your getting 18 very Constance shots from 2700psi to about 1800psi around 860fps. You'll see about 10 more shoots at the slower FPS with the regulator. After you regulate you'll need to probably have your hammer spring set lighter around 1-2 turn out. But as you know you'll need to find your sweet spot with the hammer.

If you want to keep the 860FPS you can drill about the pop valve to a .186 to get the speed back up. I've only done this on a .177 so I dont know how may shots or hammer spring adjustments for a .25.

One thing to know about Lane regulators. If you tell them to set your regulator at 125 bar they set at 130 and send you the medium sized plenum. If you tell them you want 45-50lbs they send you the larger plenum set at 125 bar.

The large plenum you have to drill a hole in the tank.

The medium you dont have to drill the tank. 

Make sure you tell them what you want. If your ok with 780FPS you dont need to drill the tank, and I'm warring you drill the tank is a pain in the rear. It's really hard to get the O-ring to slide past the hole with out clipping the rubber.



I hope this helps, 

I have a huma in my .22 bullboss. Easy to install and worth every penny. 

I have put an Audrius regulator in 2 different AT44's (same tube as the bullboss) and they worked great. One was .177 and the other .25

I have used Audrius, lane and Huma. Only one I ever saw any creep was a Huma after 3 years. I replaced the little white disc and back to working perfectly again.

I don't think yuo can go wrong with any of these. I have used 5 of the audrius main due to the cost. He sells on ebay. I've gotten them as low as $55 when buying multiples.

I purchased a used Bullboss on here with a Hatsan reg installed. It did quite well. Got 40 shots per fill and pretty consistent. I am very impressed with Hatsans barrels they are very accurate.

TheIceman,

I have put a Huma reg. in my son's Bullboss and I had it set at 140psi at the time of the order, it took 8 days to come in. We are now shooting at 825 fps with the 25.4 gr JSB for 38fpe, extreme spread is 8ft/s, StdDev 3ft/s. My son shoots it for hunting and dropped an iguana at 95 yards (87meters) and many others in the 50 to 70 yards. That baby is a killer. we get 20 rounds with that setting before dropping from the reg. I was barely able to get the max speed I had before the reg with that setting, but now every shots are at 835 fpe. The only thing I did was to de-burr the all drilling holes
