Neat fix for bulk-fill CO2 guns
Part 1

Crosman 116 pistol
Crosman’s 116 bulk-fill pistol is a .22-caliber single-shot pistol.

Today, we’ll look at the velocity of the Crosman 116 .22-caliber bulk-fill CO2 pistol. A couple things will complicate this test. First is the fact that the pistol has adjustable power. I’ll account for that with several power adjustments, but that isn’t all that’s going on.

The bulk-fill process is itself somewhat complex; because if the bulk tank doesn’t have enough liquid CO2 in it, or if the tank and the gun are both warm, the fill will be less dense and will therefore produce fewer total shots. Let’s look at the fill process before we examine the gun.

Neat fix for bulk-fill CO2 guns

Crosman 116 pistol
Crosman’s 116 bulk-fill pistol is a .22-caliber single-shot pistol with power and accuracy that surpasses many of today’s air pistols.

Before we start, a word on the “fix” for CO2 guns that Dennis Quackenbush gave me. Some folks are concerned that this will ruin the guns it’s put into. Well, it will soften the seals, and eventually those seals will dissolve into a jelly-like material that won’t seal the gun. How fast that happens depends on how much of the automatic transmission sealer you use. But here’s my thinking. The gun already doesn’t work. If this restores it to operation for a few years, or even for only a few more months, that’s more than you have now. In the end, you may need to replace all the seals anyway, but that was what you faced when you decided to do this. No permanent harm has been done. And you got some use from a gun that needed seals.
