     I recently purchased a Bulldog from grabagun.com for $537 and began modifing it for accuracy, sound, and shot count improvement. All mods were budget friendly and relatively easy for the non-skilled person. First mod I tried tackle was to regulate it for cheap.  Since there are currently no regulators, this initially appeared difficult. Until I found a paintball regulator (set at 1800psi) and bottle (390cc) for only $45!  I attached the bottle to the gun with rubber clamps and tethered it to the gun fill port.  It's heavy and cumbersome, but effective. Only a 12 ft/second spread and my shot groups at yards immediately tightend them up substantially.  Second, I tried to increase shot count.  The paintball bottle helped in this area too.  I went from 10 shot per fill to approx. 28.  With a 3800psi fill, 18 regulated at 120ft-lbs, and 10 more usable unregulated. Third mod, which only gave me a modest improvement in accracy, but a noticable one, we're extra barrel supports.  At $6 a pieace (I put in four of them),  we're a great little mod that tightened my groups by at least a .25". Fourth noteworthy mod, and the gun's most needed, was a moderator.  This gun was similar to firing a firearm and COMPLETELY not backyard or even user friendly. With the Long Pitbull Moderator, brings the gun down to "no ear plugs required" and if you tune the power down, you could even get a shot or two off in the back yard.  With the new Pitbull Moderator, it my be completely "back-yard friendly", who knows. I have not tested it

    I’m only using JSB and Hatsan 81.02 pellets.  I’m getting 1.5″ five shot groups at 50 yards, and 3.25″ at 100.  When I started, this gun I was using heavy bullets but found pellets are most accurate.  JSB at 830 ft per second were the sweet spot for me.  There is not much difference between JSB and Hatsan, expect Hatsan has a few more flyers per can. They are worth the savings if you do quick sort.

    Humma makes a regulator for it, if you want to spend the bucks for one.

    If only someone comes out with a tactical stock, I jump in n buy one.. a bulldog without a stock looks exactly like a AAA slayer.. a slayer is a custom machined  perfected bulldog .. if people buy $450 dollars stocks for airforce guns I think they will gladly pay that n a bit more for a all aluminum custom stock for a bulldog. Me included.
