Airgun silencers that are removable and can be successfully used just one time on a firearm are considered to be firearms by the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE).

Even if I weren't a writer, I would get a chronograph so I could pick the right fill level for my precharged pneumatic guns, select the best pellets for any gun and to make sure my gun is in top operating order.

I love hand pumps. They work great and are relatively easy to use even when you have to pump up to 3,000 psi. But, you have to know the right technique. I've seen strong, muscle-bound men decades younger than me who could not pump a gun up to 3,000 psi. Yet, my wife, Edith, who's as old as I am, can pump a gun to 3,000 psi. I showed her the technique, and we've never looked back! Read this article and watch the short video, and you'll also be able to pump up your guns.
