AirForce CO2 adapter is put to the test! - Part 2
by B.B. Pelletier
Well, you were certainly interested in the AirForce CO2 adapter! Judging from the comments we received, many of you see the the possibilities. As long as you are buying a PCP, it doesn't hurt that you can make it into a great CO2 rifle as well. And, if you include the MicroMeter tank, there's a third possibility from just one gun!
Before I jump into this report, a word to several readers who asked about adjusting the top hat of the CO2 adapter valve. Don't do it. The adapter uses a Condor valve, which is already set at the maximum spacing for the average gun. CO2 isn't as fussy about clearances as air anyway, so just attach the adapter and use it as it comes.
And to those who are concerned that the use of CO2 will possibly damage the seals in your gun, don't worry. First of all, all the important seals are in the valve anyway. There are only two O-rings in the gun and they just seal the rear of the barrel. And AirForce makes the adapter, so they would use the right seals for CO2.
You probably want to know how it shoots. Well, the barrels are from Lothar Walther, so you have that going for you. The day I picked for the test could not have been better. There was zero wind and a light overcast that had been fog an hour earlier. I set an intermediate target at 30 yards to get the scope zeroed, and the real target at 50 yards for the record. Unfortunately, when I tested the Logun S-16s, the wind was blowing hard, so there's no way to do a direct comparison between the accuracy of the two guns. I think they're probably equivalent. The heavy Logun trigger makes it more difficult to shoot accurately, but the potential is there.
The Talon SS was already scoped and sighted-in for operation with air, so the switch was easy. I used an AirForce 4-16x scope, which is very bright for that power. The initial groups at 30 yards were as tight as the Logun S-16s groups at 25 yards, so I knew the rifle was going to do well. And, is it ever quiet! The noise of the pellet striking the cardboard box the target was taped to 50 yards away was louder than the discharge.

The scope was mounted in B-Square AA Ultra-High 1" rings that were clamped to an AirForce Tri-Rail, which put the scope a little too high for my preference. I thought I needed the extra height, but the Tri-Rail coupled with the risers on the rings is too much. I'll lower the rings with a set of medium risers because I want to keep the Tri-Rail. It slips on all AirForce rifles fast and easy and keeps a pretty good zero when moved from one gun to another.
Both JSB Exacts and Crosman Premiers performed well. The rifle shot groups that averaged just under one inch, and the best of the day measured 0.379", though it was the only SS group that measured less than a half-inch. Because the pellet moved so slowly and the distance was so great, I could watch some of the pellets in flight.
Smallest group of JSB Exacts measures 0.379". Not bad for 50 yards!
On air, the SS is more accurate at this distance, but the difference isn't that great. I would expect to see a lot of groups between 0.50" and 0.75" on air. If the wind were blowing, the slow-moving pellet would be moved around considerably, so this long-range shooting is only possible under ideal conditions.
The Condor was snappier than the SS, obviously, and it made some noise...but nothing compared to a Condor on air. Sighting-in was very easy because the AirForce Tri-Rail permitted the scope to be transferred without a lot of change in zero.
A Condor on CO2 is still a Condor. It has as much power as some powerful spring rifles!
The Condor grouped in the 0.75" to 1.0" range, with the best group going 0.376". It also preferred Crosman Premiers and JSB exacts over all other brands. I got several JSB groups that measured just over a half-inch, and I think the extra 100 f.p.s. proved beneficial.
Five Premiers went into this 0.376" group from the Condor.
Condor put five JSB Exacts into 0.582" at 50 yards.
The bottom line
If you already own an AirForce air rifle, this adapter expands your rifle's already impressive portfolio of features. If you're thinking of buying one, here's another good reason for you. If you like the idea of precharged accuracy but don't want the hassle of the scuba tank or pump, here's the way out! Any way you look at it, this adapter adds a lot of value to the entire AirForce lineup.
