The SpecTR

SpecTR stands for Special Purpose Tactical Rifle.

The name says everything. If you load this rifle up with a carbon barrel it is the most technical shooting platform we offer at Gunwerks. It has adjustments were you need adjustments, so it can be precisely configured to your shooting application and physique. With a short carbon barrel, it offers perfect balance and light recoil with a supressor. The chassis accepts Accuracy International (AI) magazine boxes.

The System

A high tech, high end rifle NEEDS to be paired with the right scope. We prefer the new ATACR F1 rifle scopes from Nightforce. To complete the system, we can break the gun in and shoot the ballistic data. You can build a custom turret, or leave it MOA or MRAD and program your dope into the G7 ballistic rangefinder for quick ranging and ballistic solution.

The Design

The chassis stock is an amazing work of engineering and manufacturing. Painted composite skins permanently bonded to full length aluminum skeleton. Rubber grip and recoil pad with adjustable LOP. Adjustable thumbwheel cheek rest with QD mechanism. Attachment options include: flushmount rail, cupmounts and flush cups, and bottom 2″ picatinny rail.

The Shot

This system configuration is ideal for the Precision Rifle Series. Tactical competition requires a stable platform, smooth cycling, precision, accuracy and attachment capability for all the accessories you need to be successful. With a carbon fiber barrel and titanium action, the configuration makes an excellent varmint rig or ultra long range hunting rifle.

Ultra Long Range. Dial past the BDC turret with multiple revolutions of an MOA or MRAD elevation turret. Using a ballistic computer it’s easy to dial your correction in units of angle.

GLR Bolt. We’ve designed the smoothest bolt cycle possible in a twin lug bolt. The firing pin and spring are sized to enhance the firing system. The cocking helix, closing cams, and extraction ramp are timed for perfect function.  

The cheek rest is adjustable with a thumbwheel, and removes in an instant with the quick detach mechanism.

The aluminum chassis secures the action precisely without the need for bedding compound.

The tactical magazine box is secured in a patent pending cage, and you can drop the box with an adjustable paddle.

The picatinny rail position is adjustable so you can balance the rifle with the barrel contour and accessories. Flush cup mounts are available on three sides with an accessory mount on each side.

CNC equipment gives us the ability to fit the barrels precisely to our GLR action. Threading and chambering happens at high speed for smooth surface finish. The numerical control enables a class 3 thread fit.

I was impressed by it, good shooter, surprisingly light recoil for what it is, and hell, the performance is impressive to say the least.
