Bending airgun barrels: Part 1

by B.B. Pelletier

A couple weeks back, we talked about straightening bent airgun barrels to improve accuracy. We want to do that so we can hit targets with the sights that were installed. There is, however, another reason for bending barrels. Some guns have sights that do not coincide with where their barrels are pointing, even when they’re not bent. For this situation, we also need a fix.

Many guns have replacement rear sights. I own a BSF S70 breakbarrel rifle that has a Williams peep sight that was either installed by Air Rifle Headquarters (the original company in Grantsville, West Virginia) or was a sight they sold for owners to mount. ARH did inform the customers of the necessity for the rear sight to have a complimentary taller front sight installed, and on my rifle that didn’t happen. I think this was an owner-installed sight that they probably hated ever since. read more


Can a fixed-barrel airgun have barrel droop?

by B.B. Pelletier

This report is in response to a comment Pyramyd Air got from a customer who doubts that fixed-barrel airguns can ever droop. His position is that they can only have droop if the barrel is heated in some way (as on a firearm that fires very fast) or if the gun is assembled in a shoddy fashion.

He said he believed barrel droop is only commonly found on breakbarrel airguns, which is why he said he would never own one. He thought that droop was mostly caused by the metallurgy of the barrel.

Today, I’d like to address the subject of barrel droop in detail. It can be caused by many things, but poor metallurgy isn’t one of them. Barrels do not bend from cocking, despite what some people may think. It is true that a barrel can be bent by human force, but the force required to do so is much greater than the heaviest cocking effort on the most powerful magnum airgun. So, poor metallurgy is not a contributor to barrel droop. read more
