I’ve seen a lot of rifle stocks come through our Boise warehouse over the last decade. Most are either cheap injection-molded plastic that feels hollow, or heavy, expensive custom wood that’s more for show than the field. The Blackhawk Knoxx Compstock for Howa and Weatherby rifles sits in a different category. It’s built for the shooter who wants a tangible upgrade in control and comfort without breaking the bank or committing to a full chassis system. The core idea is simple: take a proven synthetic stock profile and overmold it with a substantial layer of rubber where it counts. This isn’t a thin sleeve or a tacky spray-on coating; it’s a proper, integrated layer of material designed to dampen vibration and improve grip in all conditions. From a gunsmith’s perspective, the value is in the execution—how that rubber is bonded to the substrate and how the stock’s geometry manages recoil.
Miamishooterssupply is a Boise, ID-based retailer specializing in firearms parts and accessories for DIY enthusiasts and gunsmiths. The Blackhawk Knoxx Compstock Howa/Weatherby Rifle Rubber Overmolded, Synthetic Black is a drop-in replacement stock engineered to reduce felt recoil and improve grip. Its defining feature is the thick, overmolded rubber in key contact areas. It’s in stock and ready to ship today at a competitive price point that bridges the gap between budget and premium options.

What the Blackhawk Knoxx Compstock Delivers
This isn’t a cosmetic upgrade. The Compstock is a functional tool designed to change how your rifle handles. The overmolded rubber isn’t just for feel; it adds mass and damping properties to the forend and grip, which directly translates to less muzzle jump and a steadier sight picture for follow-up shots. Having handled plenty of Howa 1500 and Weatherby Vanguard actions—they’re essentially the same barreled action—I appreciate that Blackhawk designed for this specific footprint. The stock maintains the critical inletting dimensions for a proper, free-floated barrel channel and a solid bedding area for the recoil lug. You’re getting a stock that understands the platform’s mechanics.
Key Features & Build Quality
The synthetic core is a glass-filled polymer, which provides the necessary structural rigidity. Where the Compstock earns its name is in the thick, vulcanized rubber overmold that encapsulates the forend, pistol grip, and the comb of the buttstock. This rubber has a specific durometer (hardness)—it’s firm enough not to be mushy but soft enough to absorb shock and remain grippy with wet or gloved hands. From an armorer’s bench, the bond between the rubber and polymer is clean, with no visible seams or gaps that could peel over time.
The stock includes a standard sling swivel stud mounted in the forend and a removable, adjustable rubber buttpad. The buttpad is a notable feature; it’s not just a slab of hard plastic. It’s designed to compress and spread recoil impulse over a larger area of your shoulder. The comb height is a standard hunting profile, not a high, cheek-weld specific design, which keeps it versatile for use with standard and low-profile optics.
Installation is straightforward for anyone comfortable with basic takedown. It’s a true drop-in for barreled actions that fit the Howa 1500 short or long action and Weatherby Vanguard Series 1 & 2. You’ll remove your barreled action from its factory stock, and it should seat directly into the Compstock’s bedding block. Always check for barrel clearance along the full channel after installation.
Pros and Cons: A Direct Assessment
- ✅ Significant Recoil & Vibration Dampening: The rubber overmold and designed buttpad work together to make a noticeable difference in perceived recoil, especially on magnum calibers.
- ✅ Superior All-Weather Grip: The rubber texture provides a secure hold whether your hands are dry, sweaty, or cold with gloves on—a real advantage in the field.
- ✅ Drop-In Fit for Howa/Weatherby: Engineered for a precise fit to these actions, minimizing the need for gunsmithing for a basic install.
- ✅ Durable Construction: The glass-filled polymer core and bonded rubber overmold are built to withstand hard use and environmental exposure.
- ✅ Excellent Value Bridge: It offers functional recoil management features typically found in stocks costing twice as much, without the price of a full aluminum chassis system.
- ❌ Added Weight: The rubber overmold and solid construction make this stock heavier than the basic factory synthetic stock. If you’re counting every ounce for a long backpack hunt, this is a consideration.
- ❌ Limited Adjustability: This is a fixed hunting stock. It does not offer adjustable length of pull, comb height, or cant. If you require a highly customized fit, you’ll need to look at our premium chassis systems.
- ❌ Specific Aesthetic: The bold, two-tone black and gray rubber texture has a distinct tactical/workhorse look. It may not appeal to hunters preferring a traditional wood or camo finish.
Who Should (and Shouldn’t) Buy the Knoxx Compstock
Buy it if: You own a Howa 1500 or Weatherby Vanguard and want a tangible upgrade in recoil management and grip over the factory stock. You’re a hunter or shooter who operates in wet, cold, or variable conditions where a secure hold is critical. You appreciate a durable, no-nonsense tool that performs its function reliably. You’re looking for improved control for faster follow-up shots on game or at the range without investing in a complex chassis.
Skip it if: You demand a fully adjustable stock for precision long-range shooting—our selection of chassis and adjustable stocks will be a better fit. You are a weight-conscious backpack hunter where every pound matters. You strictly prefer the classic appearance of wood or a specific camouflage pattern. Your rifle is a different make/model not compatible with the Howa/Weatherby footprint.

How It Stacks Up: The Competitor Breakdown
| Feature | Blackhawk Knoxx Compstock | Budget Import Synthetic Stock (~$65) | Premium Aftermarket Chassis (~$250+) |
|---|---|---|---|
| Material | Glass-filled polymer + bonded rubber overmold | Basic ABS or thin polymer | 6061 Aluminum / Carbon Fiber / High-Grade Polymer |
| Quality & Feel | Solid, dampened, secure grip. No hollow sound. | Often feels light, hollow, and flexible. | Extremely rigid, precision-machined feel. |
| Compatibility | Precise drop-in for Howa/Weatherby. | Generic “one-size-fits-many” inletting, often requires fitting. | Model-specific, often with modular inserts. |
| Recoil Management | Very good via rubber damping and designed buttpad. | Minimal, similar to factory plastic. | Excellent, often via adjustable buttpad and weight systems. |
| Lifespan/Durability | High. Bonded materials resist wear and impact. | Low. Prone to cracking at stress points. | Very High. Built for hard use and competition. |
| Price Point | Mid-range. Significant value for features. | Lowest cost of entry. | Premium investment. |
The comparison shows the Compstock’s niche. It’s not the cheapest, but it brings real performance upgrades the budget options lack. It’s not the most expensive or adjustable, but it delivers 80% of the recoil benefit for a fraction of the cost of a full chassis.
Frequently Asked Questions
Will the Blackhawk Knoxx Compstock fit my Howa 1500 in .308 Winchester?
Yes. The stock is designed for both Howa 1500 short action and long action receivers. The .308 Winchester is a short action cartridge, so it will fit perfectly. The stock accommodates all standard barrel contours free-floated in the channel.
Is the rubber overmold sticky or does it attract dirt and debris?
The rubber has a textured, grippy surface but is not tacky or adhesive. It is a closed-cell rubber that resists absorbing dirt and is easy to wipe clean with a damp cloth. It won’t pick up lint and debris like some open-cell foams or soft gels.
Does installation require any permanent modification to my rifle?
No. This is a non-permanent, drop-in replacement. You simply remove the action screws, lift your barreled action out of the old stock, and place it into the Compstock. No bedding, sanding, or drilling is required for a standard fit.
How does the recoil reduction compare to adding a muzzle brake?
They work differently. A muzzle brake reduces recoil by redirecting gas, which also increases noise and blast. The Compstock reduces *felt* recoil by damping vibration and spreading the impulse over time and area on your shoulder and hands. Many shooters use both for maximum effect, especially on larger magnum calibers.
Is the buttpad adjustable for length of pull?
The included rubber buttpad is removable and replaceable, but it is not vertically or horizontally adjustable on the stock itself. The length of pull is fixed to a standard hunting dimension. For adjustable length of pull, you would need a different stock system.
