How spring-piston rifles behave

by B.B. Pelletier

Okay, Grasshopper, enough Wax on! Wax off! It’s time to use your skills.

If you’ve been following the discussions over the past month about accuracy, you should now have the tools to be a pretty good judge of the potential accuracy of an air rifle and the relative ease with which that accuracy comes — even before taking the first shot. We’ll confine today’s discussion to just spring-piston guns, since they’re the most difficult to shoot.

How a spring-piston airgun works
This is a review for many of you, but we have enough new readers that perhaps it’s good to go over the points of how the spring-piston gun works. What I’m about to say holds true for guns with gas springs as well as guns with coiled steel mainsprings. They all work the same when it comes to their operation. read more

Cybergun brings us this Mini Uzi BB submachine gun. Owners think it’s accurate and today we’ll find out.

Today is accuracy day with the Mini UZI CO2 BB Submachine Gun by Cybergun and I have been awaiting this day with great expectations. That’s because almost every owner review I’ve read about this gun emphasizes how accurate it is. Today, we’ll find out.

To be the most accurate BB submachine gun I have tested, this gun will have to beat the EBOS from Umarex that I tested for you in November 2010. That gun was truly phenomenal at 15 feet on full-auto. About 40 full-auto shots could be covered by a half-dollar. read more

Cybergun brings us this Mini Uzi BB submachine gun.

This gun’s last report had lots of good comments from owners and from those who have been researching it. I think the most powerful feature it has is the fact that it fires from the open bolt. When you shoot, a heavy mass reciprocates in mock recoil. It’s the difference between an M3 grease gun that jumps all over the place when it fires and an HK MP5 that barely recoils at all. This Mini UZI CO2 BB Submachine Gun by Cybergun really jumps around.

I can see why people are impressed by its performance in full-auto. It feels so realistic with that heavy steel bolt working back and forth on every shot. read more
