The history of airguns is fascinating to those who enjoy applied creativity. But sometimes when creativity is carried too far it becomes a liability. And that’s the case with today’s guns.
Rocky Mountain Arms Corporation
In the 1970s the Rocky Mountain Arms Corporation (RMAC) created a little gun for kids who wanted to shoot with their fathers. They referred to it as a .22 caliber, though it shot a number 4 buckshot that is really 0.24 inches rather than 0.223 inches in diameter. That didn’t matter because a 5-pound bag number 4 buckshot was available for a few dollars. For that you got thousands of shots. Nobody worried about the size of the ball that much.
The Bersa BP9CC is a small sidearm. It’s slightly larger than a pocket pistol, which is diminutive for a sidearm. It’s a close copy of the Bersa Thunder firearm that chambers the 9X19 (Luger) cartridge. The pistol I am testing is a two-tone gun with a silver slide and black frame. The slide is metal and the frame is polymer — similar to many new handguns today. Because the gun is small, the grip is both slim and comfortable for average adult hands.
Today we learn whether the TAC-4.5 BB gun from ASG can shoot. We already know it is quiet, has a nice trigger and is very conservative with gas. Accuracy is the cherry on the sundae. The distance was 5 meters.
Air Venturi zinc BBs
The first BB tested was an Air Venturi silver (zinc-plated) BB. Seven of them went into an incredible 0.727 inches at 5 meters. The other 3 BBs opened the group to 1.877 inches. I think those 3 shots were caused by aiming errors, because the front sight has an red fiberoptic bead that is larger than the entire bull on a 10-meter rifle target.
Today is the velocity test of the TAC 4.5 BB gun. This airgun operates on a single 12-gram CO2 cartridge that is housed in the grip. In Part one I showed you how the spring-loaded backstrap flips back to reveal where the cartridge goes.
I noted there was very little gas escape when I pierced the cartridge, and the gun seems very quiet. But a hole in the backer cardboard told me the gun definitely shot.
ASG Blaster BBs
I’m going to get right to it today. The first BB I’ll test is ASG’s Blaster steel BB. I measured 5 of them, and the diameter ranged from 0.171 inches to 0.173 inches. One of the five was out of round by a thousandth of an inch. The other four were regular. This BB is on the smaller side of what is normal for BBs today (0.171 to 0.173 inches), and the variation in size is greater than I have seen. We will see what that means, as far as accuracy is concerned.
A couple weeks ago, several readers had a discussion on the blog about shooting the Colt Single Action Army BB revolver with pellets. I didn’t read everything they said in detail, but the basic idea stayed with me for several days until I began to wonder, “Why not?” Back in 2013, I tested the Diana model 25 smoothbore pellet gun and discovered that it’s very accurate out to 10 meters — even though there’s no rifling to spin the pellet. Why wouldn’t this BB revolver also be accurate?
Today, I’ll start a report on the ASG TAC-4.5 BB gun. It’s called the TAC-4.5 BB rifle on the Pyramyd Air website, but it is a BB gun. It is not rifled and of course it isn’t 4.5mm. BBs run around 4.3mm. But they are so closely associated with pellets that the industry lumps them together, using the same size label.
The TAC-4.5 is a 3.5-lb. BB repeater that feeds steel BBs from a 21-round stick magazine located in a removable carrier. This magazine does not contain the CO2 cartridge. Spare magazines are available.
The pull is 13-3/4 inches. The overall length is 35 inches on the button. The buttplate is a grippy, soft black rubber pad that prevents the gun from slipping when it stands in the corner.
This will be our final look at the Black Ops Junior Sniper air rifle combo. Today, I’ll mount the scope and shoot the rifle from 25 yards. I thought this report would just be about the rifle and scope; but, in fact, I learned 2 other very important lessons. So, today’s blog will be informative. There are also two short instructional videos.
The scope that comes with this combo is the cheapest kind of optical sight you can buy. It’s a 4x scope with a very skinny tube – less than .75 inches. The rings come already attached, so all I had to do was clamp them to the top of the rifle, and the job was done. That said, I had no idea if the scope would even be on the paper at 25 yards.
