LongSword  S.W.S.       The Specialty big brother to the SENTINEL 

TM

The LongSword is a specialty rifle designed for heavy lift/penetration or extended range duties.  Certain jobs require maximum energy on target, the ability to defeat barriers, extended range target reduction or a combination of these needs.

 

LongSword can fill many of these needs while maintaining the same functionality and similar handling of its smaller SENTINEL cousins based on  short aciton receivers. 

SCALED UP ACTION

The base of these rifles is the KMW LongSword Mk-2 Magnum action produced by Defiance Machine in Montana.  As with the Mk-1 short actions, the Mk-2 offers similar mission specific features that are machined integral to the receiver from one block of steel.  All final dimensional machining is completed after heat treat.  The center bore and lug raceways of the receiver are EDM wired leaving an inside dimension that runs parallel to the exterior within 0.001" 

 

Some of the main features of this action are: 

     Larger 0.750" diameter bolts on the Lapua and Norma calibers to properly support the 416 Rigby sized case heads.

     Rem M700 Long Action style footprint.

     Integral 20 M.O.A. Picatinny 1913 Mil-Spec base.

     Integral .250" recoil lug. 

     23% longer barrel tenon thread increases engagement and rigidity. 

     Heavy duty, side mounted bolt release.

     Heavy duty Mini-16 Extractor.

     Bolt handle base is machined integral to the bolt body so there are no welds or brazing to break.

     KMW Gen II Handle.

BARRELS

I use only match grade, cut rifled barrel blanks from Krieger Barrels .  These blanks are manufactured in Wisconsin, USA.  The minimal stress of the cut rifling process allows a barrel that is very well behaved through a wide temperature range.  Each blank is precision machined and chambered by KMW for perfect alignment.  Certain clearances and fit tolerances are tailored to allow for operational extremes.

 

Variants of the LongSword S.W.S. will be offered with differing barrel lengths and suppressor mounting options.

 

Chamberings for the LongSword include:  .300 Win.Mag., .300 Norma Mag., .338 Lapua Mag., and .338 Norma Mag.

 

TRIGGERS

Triggers are supplied by Timney Manufacturing.  I have found the new generation Model 510 to be extremely reliable and rugged.  Customers opting for lighter pull weights have the option of substituting the Timney Calvin-Elite.

 

STOCKS

Each LongSword S.W.S. rides in a proprietary stock designed by KMW.  The raw stock bodies are manufactured by McMillan Fiberglass Stocks in Phoenix, AZ.  Each stock then has all hardware installed and additional cuts made by KMW to make it build ready.  This stock design was developed over a period of 4 years.  It includes input from top competition shooters as well as Law Enforcement agencies from different parts of the country.

 

This stock was dubbed the SENTINEL Combat Stock and features an ambidextrous thumbhole grip and adjustable cheek piece design.  Unique features include a very low profile forend with comformal bottom optimized for the excellent Harris S-Series bipods.  A user swappable plate system allows the substitution of a supplied 1913 Picatinny Rail for those wanting to utilize the Accu-Shot or similar bipods.

 

Marble and Camo patterns are molded into the Gel Coat outer layer of the epoxy shell which allows for extreme durability and excellent long term cosmetics.

 

Each KMW LongSword S.W.S. rides in a version of this stock that includes  a precision machined Integrated Mounting Block or I.M.B. in lieu of conventional bedding.  This system has proven itself in duty and competition environments and carries a Lifetime warranty.

 

Every SENTINEL stock includes LoggerHead adjustable cheek piece hardware, KMW Adjustable Length of Pull spacer system and KMW designed DBM bottom metal that fully blends and integrates seamlessly with this stock. 

 

KMW MUNSter PVS-22/27 forward Night Vision mount can be specified on these packages.  More information on the MUNSter NV mount can be seen by clicking here > KMW MUNSter NV Mount.

METAL FINISHES

Bolt Body, Firing Pin and Cocking Piece are coated by I.H.I. IonBond with a dark gray DLC finish for extreme durability and low maintenance.

 

Balance of metal components are coated in house with CeraKote "H" series ceramic hybrid finish.  Base colors are suited to the spec of each group of rifles.  Some groups of rifles will feature our MIRAGE 2 or 3 color CeraKote application.  This features one or two contrasting color bands over the base color.  Soft transitions from one color to another provides superior camouflage to sharp edge changes often seen when stencils are used.  I believe that the softer transition of colors with the MIRAGE pattern offers an effective shadow type breakup camo that is superior to smaller detail patterns when in the field.

 

OPTICS

LongSword S.W.S. can be delivered with Vortex HD optics or NightForce optics and rings as specified by the client.  You also have the option to supply and ship these or other another optic of your choice to KMW and mounted to your S.W.S. prior to delivery/shipment.

 

VARIANTS

The LongSword is typically built as an "all up" rifle.  Default will be full loadout including MUNSter NV mount and muzzle break/suppressor adapter as standard features.

 

 

 

 

 

 

PERFORMANCE

All rifles go through multiple thorough inspections.  Bore break in is done and all rifles are tested for accuracy as well as function  before release for delivery to the client.  All LongSword S.W.S. are guaranted to group 1/2 M.O.A. or better @ 100 yds with match quality ammunition. Each rifle must fire 3 consecutive 3-shot groups on one test target to be released for delivery.  This ensures that I have a healthy rifle and you are not getting "cherry picked" groups.

 

If your rifle fails to perform, I will fix the problem part at no charge unless there are obvious signs of neglect or abuse.  My name is stamped on every rifle because I think a rifle smith or business should be accountable for the work being delivered.  All of my rifles are built to be used!  I do not ship a rifle unless I would be willing to bet my own skin on it.  All work is guaranteed.

 

DELIVERY and PRICING

Pricing of the LongSword S.W.S. will vary depending on the exact specs for each group.  As each group of rifles are completed and made available, a downloadable PDF file will be available showing exact pricing and specifications.  Delivery of "Spec" rifles would be within 2 weeks of initial order confirmation. 

 

Agency RFQs and RFPs are welcome.  Pricing and delivery will be based on your exact specifications and the number of S.W.S.s being quoted.
