Our aftermarket .22LR Black “tapered
bull” barrel is a great long barrel look without the weight. Tapering to
.700” at the muzzle the balance point for the rifle is very close to the
shooter’s body thus reducing the “felt” weight of the rifle. Our blued chromoly
material along with 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.
Our tapered 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 including hand lapping
each barrel. A proprietary chamber reamer is used to ensure the cartridge and
bullet feed smoothly. Our barrels are chambered to accept .22 LR 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.
Barrel weight:
20" tapered match barrel= 2
pounds 12 ounces (lighter than a 16.5" bull 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.
