REBARRELLING
"Set Your Sights on The Best"
Barrel
Blanks
We
only purchase Match-grade Barrel Blanks from manufacturers who guarantee their
product has the best available tolerances. Both Select Match Stainless and
Match-grade Chrome-moly barrels can be fitted. Parallel, rifled blanks are
purchased and all additional machine work, except fluting, is completed
in-house.
The
standard lengths are up to 26" for Shilen and Krieger. Longer blanks can be obtained but, except for standard NRA 30cal x
30" target rifle barrels, will carry a surcharge of £15 per inch. A good
selection of barrel twists are available from 1 : 7 to
There
are so many high quality barrel makers that the choice is often personal
preference. We carry a stock of the common bore sizes and twist rates from
Krieger and Shilen. In addition, we occasionally have Lilja, Bartlein and Hart blanks in
some specifications and will be pleased to supply any barrel from these
manufacturers. Krieger cut rifled barrels are having good success in the competition world and are proving to shoot well for us. Krieger have installed cryogenic treatment facilities and are treating all blanks before beginning to machine them. They report that the blanks are easier to machine with the result being a straighter hole. Although the advantages may be academic it makes chambering the blank with a concentric chamber simpler if the bore is straight.
Fitting
Accurate
rifles require barrels and actions
to be squarely aligned to achieve maximum performance. With this principal in
mind, the barrel is carefully threaded to ensure a perfect fit. This work is not
readily visible but is essential to reach its full accuracy potential.
Considerable amounts of capital have been invested in purchasing equipment &
tooling which allows us to work to the tightest tolerances and we are constantly
upgrading our machinery to keep at the forefront of technology.
Chambering
Our
chamber reamers are ground to SAAMI, CIP or Custom dimensions with minimum
tolerances and are used only in conjunction with 0.0001" increment
interchangeable pilots. Currently we have over 120 different reamers to choose
from; please refer to our current list.
We
commonly change the calibre/chambering of a sporting rifle during rebarrelling.
Providing the bolt face and magazine length are suitable then we are pleased to
discuss any appropriate changes.
Notes
Please
bear in mind that the barrel channel in the stock will often have to be
increased to suit a larger diameter barrel, this is not included in the cost of rebarrelling.
We
will be pleased to carry out any servicing work required to action or trigger
while the barrel is being replaced but this should be included in a letter of
confirmation to be sent with the rifle. A quote can be provided for all work if
required.
Proof
Testing All complete rifles, & re-barrelling jobs, have to be sent to one of the Proof Houses to be test fired; we currently use the London Proof House. We request that all our proof marks are engraved onto the barrel as this leaves a much neater finish.
Profiles
Barrel
profiles can be machined to suit any requirements to optimise weight, balance
and accuracy. We have a selection of approximately thirty different shapes that
we commonly use. Any straight taper can be cut providing details of the muzzle
diameter and length are supplied with the order. Special profiles, for which we
do not have the masters, can be machined but they will incur a set-up charge
which will be based on our standard hourly rate.
We
offer barrel finishes in polished and bead-blasted (matte) for stainless steel
and machine polished black or matte black for chrome-molybdenum steel. Chrome-moly
barrels can also be hand polished for a traditional high gloss finish.
All
barrels supplied and fitted by Precision Rifle Services Ltd carry a full
guarantee. If the barrel does not perform the way that we consider appropriate
and is returned to us within sixty days of supply, it will be exchanged at our
discretion.
In
order to keep the costs of rebarrelling down, testing and load development are
not included in the price. If a rifle is returned and is subsequently found to
shoot acceptably the costs of load development work will be covered by the
customer at our current charge of £150 plus carriage.
Please bear
in mind that the barrel is not the only component which
will
influence the accuracy of a rifle.
