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.
