Proof Research Stock Models at Mile High Shooting
Mile High Shooting stocks two Proof Research carbon fiber stock models. Both share the same hand-laid construction, Sendero barrel channel profile, and sub-21-ounce target weight. The differences come down to profile, action length availability, and ergonomic preferences.
Lightweight Hunter Stock
The Lightweight Hunter is Proof Research's hunting-profile carbon fiber stock, designed for shooters who want significant weight savings over conventional composites without sacrificing accuracy or field durability. The stock uses bedded pillars and a molded-in carbon fiber V-block for consistent, repeatable action fit shot after shot. The Sendero barrel channel accommodates heavier Proof Research barrel contours with clearance to float the barrel properly. Available at Mile High Shooting for compatible short action builds only.
Specifications:
- Action compatibility: Zermatt Arms TL3/SR3 SA, Defiance Ruckus Hunter SA
- Overall length: 30 ¾ inches
- Length of pull: 13 ⅝ inches
- Barrel channel: Sendero
- Construction: Hand-laid carbon fiber with bedded pillars and molded-in carbon fiber V-block

Lightweight Tactical Hunter Stock
The Lightweight Tactical Hunter is the feature stock on Proof Research's Elevation MTR rifle, bringing a more tactical-oriented ergonomic profile to the same lightweight carbon fiber construction. It features a near-vertical pistol grip and a raised comb for a consistent, high cheek weld suited to modern precision optic heights. Like the Lightweight Hunter, it uses bedded pillars, a molded-in carbon fiber V-block, and a Sendero barrel channel. The Tactical Hunter adds long action availability, making it the right choice for shooters building on the Zermatt TL3/SR3 LA platform. Available at Mile High Shooting for short and long action builds.

- Overall length: 32 ¼ inches

Choosing the Right Proof Research Stock
Both stocks share the same carbon fiber construction and core performance characteristics. The choice comes down to your action size, whether you need long action compatibility, and which ergonomic profile fits your shooting position.
Action Compatibility
Mile High Shooting stocks Proof Research stocks pre-fit for two action platforms: Zermatt Arms TL3 and SR3, and the Defiance Ruckus Hunter. These are short action in both models, with long action available in the Lightweight Tactical Hunter for Zermatt TL3/SR3 LA builds. If you are running a different action, contact Mile High Shooting before ordering, as availability outside these platforms is limited.
Hunting vs. Competition Use
For backcountry hunters carrying a rifle over long distances, the Lightweight Hunter's traditional profile keeps weight at an absolute minimum. Paired with a Proof Research Sendero carbon fiber barrel on a Zermatt TL3, the complete barreled-action-and-stock package comes in under 5 pounds before optics, making it one of the lightest precision rifle setups available for field use. For competitors who shoot from positional barricades and need more consistent cheek weld height with modern tall optics, the Lightweight Tactical Hunter's raised comb and near-vertical grip provide a meaningful ergonomic advantage without adding meaningful weight.
Long Action Builds
Only the Lightweight Tactical Hunter is available in a long action configuration at Mile High Shooting, currently for the Zermatt TL3/SR3 LA. Shooters building a long action precision rifle in calibers like 6.5 PRC, .300 Win Mag, or .300 PRC on a Zermatt platform should spec the Lightweight Tactical Hunter LA. The Lightweight Hunter is short action only and currently available at MHSA.
Proof Research Stocks FAQs
What actions are compatible with Proof Research stocks at Mile High Shooting?
Mile High Shooting currently stocks Proof Research Lightweight Hunter and Lightweight Tactical Hunter stocks pre-fit for Zermatt Arms TL3/SR3 (short action and long action) and Defiance Ruckus Hunter (short action). These are the only configurations in stock at MHSA. Proof Research produces stocks for additional action platforms through their direct sales channel, but availability at Mile High may vary. Contact the MHSA team to ask about specific action compatibility before ordering.
What is the difference between the Lightweight Hunter and the Lightweight Tactical Hunter?
Both stocks use hand-laid carbon fiber construction with bedded pillars and a molded-in carbon fiber V-block, and both weigh under 21 ounces. The Lightweight Hunter uses a traditional hunting stock profile and is available in short action only. The Lightweight Tactical Hunter uses a near-vertical grip and raised comb for better cheek weld with tall precision optics, and is available in both short and long action.
What barrel channel profile do these stocks use?
Both Proof Research stock models use a Sendero barrel channel profile, which accommodates the heavier Sendero-contour barrels common in Proof Research's bolt-action lineup. Lighter hunting contour barrels will have additional clearance in the channel, which does not negatively affect accuracy since the accuracy-critical fit is at the bedding surface and V-block, not the barrel channel. Proof Research pairs these stocks with their Sendero contour barrels across the Elevation and Glacier rifle platforms.
