New Adjustable Cheek Piece using Eliseo Tubegun Parts

Forum member Mike T. (aka “Watercam”), has cleverly adapted a tubegun cheek piece to conventional fiberglass and wood stocks. The cheek piece hardware comes from Competition Machine and is the same as used on Gary Eliseo’s tubegun stocks. Here is Watercam’s Project Report:

Installing Tubegun Cheek Piece on Conventional Gun Stock
All of my match rifles are equipped with thumb-wheel adjustable cheek pieces for the best of reasons — adjustments can be made while in position, on target. I’ve learned that variations in position, terrain, and vertical angle all demand adjustability to achieve optimal cheek weld.

I wanted a cheek piece for my hunting and tactical type stocks that gave the same adjustability without having to cut a chunk off of my butt stocks. It needed to be affordable and easy to install. I also wanted a unit that would not push my head laterally away from the centerline of the scope or iron sights. Turns out I already had what I needed on my Gary Eliseo B-1 tubegun. I ran the idea past Gary, who said: “If you’ll be the guinea pig I’ll send the hardware”.

Using Gary’s hardware, I mounted Eliseo alloy thumb-wheel adjustable cheek pieces on a Bell & Carlson Medalist hunting stock and a Boyd’s laminate tactical stock. Read Forum Discussion.

Building Version One on Bell & Calson Stock
I had a Bell & Carlson Medalist stock for a Mauser 98 chambered in 9.3×62. This test rifle was enough of a thumper to reveal if the metal cheek piece could handle strong recoil.

I started by drilling three 1/2″ holes into the top of the comb to match the two pillars and one threaded shaft on the cheek piece. I used aluminum tubing to make guides for each and epoxied them in place. Inletting the oval hole for the thumb wheel was reasonably straight forward and the fiber reinforced foam in the buttstock offered enough support. A large flat washer epoxied underneath where the thumbwheel lay gave a smooth bearing surface. Total adjustment (with 2.25″ pillars and shafts) is just about an inch. I chose to trim the bottom of the skirt of Gary’s cheek plate so as to allow better position behind the scope for me and allow maximum adjustment even with the cheek piece of the stock. Set screws could be used instead of the thumb-wheel or in conjunction with it. In the end it was exactly what I envisioned and works great! The only thing left to do is paint the metal to match the stock.

Version Two — Installed on Boyds Laminated Tactical Stock
Watercam’s second metal cheek piece installation was on a laminated tactical stock. This Boyds stock did have a movable comb, but the original adjustable cheek section was too awkward to adjust from position. So I adapted the Eliseo cheek piece to to the Boyds stock, as you can see:

Cheek piece installation for both stocks was straight-forward, and the new cheek pieces work every bit as well the systems on my match rifles. Aluminum tubes epoxied in place guide the rods and threaded shank. A matching-diameter flat washer epoxied under the wheel provides smooth bearing surface. The glass-filled filler of the butt stock is plenty strong enough to support the unit. A set screw and knob can be added to lock in changes if so desired.

New Speedy-Designed Competition Stocks from Shurley Brothers

Shurley Brothers ARK Speedy Gonzalez stock competition F-Class Benchrest

Benchrest Hall-of-Famer Thomas “Speedy” Gonzalez has teamed up with the Shurley Brothers on a new ARK series of wood laminate competition stocks. Speedy has combined the best features of various popular F-Class and Long-range Benchrest stocks into new designs to be produced by Shurley Brothers Custom in Austin, Texas. These stocks should be very straight and geometrically correct as they will be crafted on the Shurley Brothers’ new CNC mills. These stocks will be made with new-generation precision technology, not old school duplicating machines.

Initially two models will be offered: the “Hand of God” (HOG) and the “Spear of Destiny” (SOD). Both are designed for multiple shooting disciplines, so they should work well both for benchrest and for prone F-Open shooting. (FWIW, John Myers used a Speedy-crafted stock to win the 2015 Mid-Range National Championship). The forearm is 76mm (2.99″) to comply with F-Open limits. A wide variety of options will be available including adjustable Cheek Piece, adjustable length of pull, carbon fiber inserts, and exotic woods.

We like many aspects of the new stocks. First, the front of the stock is low profile, placing the barrel close to the bags for better tracking (and less hop). However, a deeper (top to bottom) section extends forward of the action — this is important. We have seen some low-profile stocks that suffer from forearm flex/hinging because they don’t leave enough wood under the action area. Speedy’s design eliminates this problem. Another nice feature of this stock is the subtle curve from the back of the action to the buttpad mount. Speedy calls this the “scooped cheek”. This allows the “driver” to shoot without face contact if he prefers, but it also allows for a higher buttpad position — which is useful when shooting heavy recoiling chamberings such as the .300 WSM.

Note how the comb area has a curve to provide clearance. For those shooters who prefer to have face contact on the gun, an adjustable Cheek Piece is offered.

Shurley Brothers Custom says these new ARK stocks are fully customizable for competition shooters with optional carbon fiber, adjustable R.A.D. systems, and many other features. The stocks, uninletted, will run $750.00. CNC-inletting (for action of your choice) is an additional $100.00. Here are some of the many available options:

— Pillar Bed and Inlet: $425.00
— Custom Wood Upgrade (Price Dependent On Wood): $100.00 – $500.00
— Full-length Carbon Fiber Stringers: $200.00
— Cheek Piece Addition: $100.00
— Cooling Ports (Buick Vents): $60.00
— R.A.D. System #2A: $335.00 (plus $100.00 to install)
— 3-Way Butt Plate: Call for Price
— Adjustable Neodymium Magnetic Cheek Piece: Call for Price
— Install Neodymium Magnetic Cheek Piece: $150.00
— Stock Finish & Clear Coat: $350.00
— Carbon Fiber Forearm Tunnel: $300.00

The underside of the forearm is relieved in the center, leaving twin outboard rails. This helps stabilize the rifle and aids tracking. (A conventional, flat forearm without rails tends to rock if there is any hump in the middle of the sandbag). Between the rails is a carbon-fiber stiffening insert.
