Our aftermarket pistol bull barrel is a precise upgrade
for your Ruger® 10/22® Charger™. Our stainless-steel
material along with our unique manufacturing procedures will increase your
accuracy.
We believe these are the
finest barrels on the market, each one is hand lapped. Our stainless-steel
barrel is bored and rifled by Lothar Walther in Germany. Tony Kidd then
performs all the final machining to make our pistol barrel a worthy KIDD
product. A proprietary chamber reamer is used to ensure the cartridge and
bullet feed smoothly. Our barrels are chambered to accept .22LR ammo and have a
1:16 twist.
The unique convex
extractor slot eliminates extraction problems by ensuring the extractor is
always in perfect alignment with the case rim. Why doesn't everybody use this
extractor slot? Because the tooling is very expensive and requires tolerances
be held very close for proper machining. Each barrel receives an 11-degree
crown and the double ring at the muzzle end with KIDD marked on the barrel.
Avoiding "barrel
droop":
First and foremost,
barrel droop is eliminated with a solid fit between the barrel and the
receiver. If the barrel slips in too easily then the shooter should already be
aware that there is not a secure fit and gravity will start doing her work
immediately. Or if the barrel tenon is not the same diameter throughout the
length then a teeter totter effect is set in motion. For instance, if the
breach end of the tenon is smaller than the shoulder end the weight of the
barrel will "pull" the barrel down and barrel droop is created. Or if
the breach end of the tenon is larger than the shoulder end then as the tenon
is installed in the mortise the breach carves a larger hole and again a teeter
totter effect is created as the smaller shoulder end of the tenon sits is a
hole that is too large. This same effect would happen if the middle of the
barrel tenon was enlarged.
KIDD eliminated barrel
droop with the utilization of a resistance fit in this mortise and tenon joint,
meaning that the KIDD barrel tenon is just slightly larger in diameter than the
KIDD receiver mortise and we make certain that the tenon is the same diameter
throughout the length.
Another problem area to
be aware of is the proper utilization of the shoulder. If the shoulder of the
barrel does not set flush against the receiver, the support isn't there.
Comparable to setting down a tall glass with a convex bottom, it wants to tilt.
We make certain that the shoulder created between the .920" diameter and
our tenon is precise. This requires specialty cutting tools to create a very
clean step. But if done with less care there will be a ramp rather than a step
between these two differing diameters. This ramp will not support the necessary
weight and will prevent the shoulder of the barrel from sitting flush against
the receiver.
When this barrel fitment
is secure, we recommend the v-block screws just need to be snug, around 10-inch
pounds, which is just snug enough to keep the barrel from moving forward, but
not too tight to pull the barrel out of alignment.
Barrel installation:
Depending on your
receiver, if there is paint built up in the receiver mortise be sure to scrape
that out. We recommend using an anti-seize compound to assist in installation.
Anti-seize is readily available at automotive stores or in our maintenance tab.
It is best if you can get the barrel tenon started into the receiver mortise,
then turn it over and tap the back of the receiver with a rubber mallet. Be
sure to line the extractor slot up as you are installing the barrel. Your
barrel is ready to shoot, just run two magazines through it before you really
start looking at group size. Do this each time you change brands of ammunition
as well. Keep the chamber clean, but don't clean the bore too much, you will
decrease accuracy. Depending on the ammo, clean the bore around every 500
rounds.
