Our aftermarket
.22LR black bull barrel is the ultimate performer in accuracy. Our unique
manufacturing procedures guarantee that our match barrel will group 1/2"
at 50 yards. This bull barrel will slip into your Ruger® 10/22® receiver or
other aftermarket 10/22® receiver. The best thing about these match bull
barrels are their simplicity. They tend to be more nose heavy than our other
barrels but, in this way, they create an advantage while target shooting. The
advantage is created by slowing down the movement of the rifle. When the rifle
movement is slow the target appears for a longer amount of time in the scope.
We believe
these are the finest barrels on the market, each one is hand lapped. Our
chromoly barrel is bored and rifled by Lothar Walther in Germany. Tony Kidd
then performs all the final machining to make our match 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.
