O-rings

The fun part of being a block officer for the BSWN was that when I wasn't shooting, I was helping run the line for the F-Open crowd... and got to see some of the toys that the R&D division of F-class is playing with.

Speaking of which, something I saw on more than a few guns was O-rings on the barrels. Some had regular tuners plus O-rings, others just straight cylinder barrels. For the most part they were all F-Open guns, but there might have been one or two F/TR guns with the rings on there, about 6 inches back from the muzzle.

A couple people I talked to since then said they basically had a gun that they couldn't quite dial in to their liking, and out of desperation tried the O-rings, and kept adding til the groups flattened out the way they wanted.

It sounds like they were basically making a DIY (and less fugly) version of the LimbSaver Deresonator, as it doesn't seem possible that a handful of O-rings would add enough mass to function as a normal tuner. Unfortunately, there didn't seem to be a whole lot of method to the madness, beyond keep adding more until it stops improving. Nothing about finding the best location, etc. which would make me think that it was total B.S. / snake-oil. That said, some of the shooters using them (like @Zilla aka David Gosnell) were shooting very, very well!

Anyone here messed with these, and willing to admit it? ;)

Monte, have seen similar attempts at favorably altering bbl harmonics with limbsaver-types, even windings of electrical tape in rim fire. It seems to me, as you point out, that the typical masses involved are trivial. If converting mechanical energy into heat, to dampen bbl harmonics, they fail. However, have a design that will do so, at least in rimfire. Simply look at a compound bow, and how the damper is attached. Do they remove vibration? One shot confirms. Materials science aimed at bbl frequencies aside, the basic device must be cantilevered. Seymour
