You’re looking at the SSAR-15 OGR Bump Stock, and you’re probably thinking about the mechanics. I get it. As a gunsmith, the first thing I do is strip a part down to its core function. This isn’t just an accessory; it’s a specific mechanical interface for your AR-15 platform rifle. The ‘OGR’ designation isn’t marketing fluff—it stands for ‘Original,’ referencing a specific design lineage known for its straightforward, robust construction. At Miamishooterssupply, we see a lot of components come through our Boise warehouse, and what sets this apart is its focus on delivering a predictable, repeatable function without unnecessary complexity. It’s a tool for a specific type of recreational shooting, built to a price point that makes experimentation accessible.

What the SSAR-15 OGR Bump Stock Delivers
From an engineering perspective, the value here is in its singular purpose. This stock replaces your standard buttstock and provides a free-sliding channel. The rifle’s recoil, combined with maintaining forward pressure with your non-firing hand, allows the firearm to slide back and forth, resetting the trigger and facilitating a rapid rate of fire. It’s a purely mechanical process. The OGR model typically features a simpler internal mechanism and a more basic polymer shell compared to higher-end models, which translates directly to its accessible price. For the tinkerer or the shooter who wants to understand the principle without a major investment, this is the entry point.
Features & Build Quality
The construction uses a glass-filled polymer for the main housing. This isn’t the ultra-high-end nylon you’d find on a $250+ unit, but it’s a significant step above the brittle ABS plastics common on sub-$80 import knock-offs. The glass fill adds rigidity and heat resistance, which matters during extended use. The finish is a standard matte black, not particularly grippy, but it won’t snag on gear.
Internally, the slide mechanism runs on metal rails or channels. Wear is the primary concern with any sliding part, and these contact points are the heart of the unit’s lifespan. The hardness and finish of these rails are decent for this tier. They’re not tool-steel hardened, but they are machined adequately to prevent rapid galling. You’ll want to keep them lightly lubricated. The spring that returns the stock forward is a critical component; on this model, it’s a serviceable music-wire spring. It’s not over-engineered, but it’s replaceable if it ever wears out.
Installation is straightforward for anyone familiar with an AR-15 buffer tube. You remove your existing stock, slide the OGR onto the buffer tube, and secure it with the included locking mechanism—usually a set screw or latch. Compatibility is broad: it fits any mil-spec diameter buffer tube. It will not fit commercial-spec tubes, so verify your lower receiver’s spec before ordering. This is a common point of confusion I see daily.
Pros and Cons: A Gunsmith’s Take
✅ Pros:
- Cost-Effective Entry Point: At $155, it sits in a practical middle ground between questionable cheap imports and premium brands.
- Simplified, Serviceable Design: Fewer small parts mean fewer potential failure points. The design is easy to disassemble for inspection or cleaning.
- Wide Compatibility: Works with any rifle-length AR-15 upper on a mil-spec lower. This covers a massive portion of the market.
- Predictable Function: When used as directed, it provides a consistent, mechanical rate of fire. There’s no electronics or gimmicks.
- Ready Availability: We keep these in stock in Boise, so you’re not waiting on a slow boat from an unknown supplier.
❌ Cons:
- Material Compromises: The polymer shell and internal rails are good, not exceptional. For ultra-high-volume shooters, the wear life will be shorter than a premium metal-bodied unit. If durability is your absolute top priority, you may want to browse our stocks category for higher-end alternatives.
- Basic Ergonomics: The shape is functional but not contoured for maximum comfort during extended shooting sessions. It’s a blockier profile.
- Requires Technique: Like all mechanical bump stocks, it requires proper stance and hand placement to function reliably. It’s not a ‘plug and play’ full-auto simulator; there is a learning curve.

Who Should (and Shouldn’t) Buy This
Buy the SSAR-15 OGR Bump Stock if:
- You’re a mechanically-inclined shooter who wants to understand how this type of device functions without a huge financial commitment.
- You engage in recreational shooting where this device is permitted and want a reliable tool for that specific purpose.
- You value having a domestic supplier with inventory ready to ship, avoiding the gamble of international e-commerce.
- You’re comfortable with basic firearm maintenance and the concept of a consumable accessory that may wear with use.
Skip the SSAR-15 OGR Bump Stock if:
- You demand the highest possible durability for thousands of rounds of use. Consider a premium, metal-bodied model instead.
- You are unsure of the legal status of such devices in your jurisdiction. It is your responsibility to know and comply with all federal, state, and local laws.
- You expect it to function like an actual automatic sear with zero input. It requires practice. If you want a different type of trigger experience, check out our drop-in trigger options.

I always recommend seeing a product function before you buy. YouTube is an invaluable resource for this. You can find disassembly videos, installation guides, and live-fire demonstrations. Pay attention to the shooter’s hand placement and stance—it’s key to making it work.
Frequently Asked Questions
Where can I buy a bump stock online?
You can order the SSAR-15 OGR Bump Stock online right here at Miamishooterssupply (miamishooterssupply.com). We are a U.S.-based retailer in Boise, ID, with inventory ready to ship.
Is this legal to own?
Laws regarding these devices vary dramatically by state and locality. As of our last update (March 2026), federal law permits ownership, but several states have enacted bans. It is the sole responsibility of the purchaser to know and comply with all applicable laws before ordering. We do not ship to prohibited jurisdictions.
Will this fit my AR pistol or rifle?
It will fit any AR-15 pattern firearm (rifle or pistol) that uses a mil-spec diameter buffer tube. It will NOT fit commercial-spec buffer tubes. Most factory rifles use mil-spec, but many aftermarket stocks use commercial. Check your existing stock or buffer tube specifications.
How difficult is it to install?
Installation is simple if you can change a standard AR-15 stock. It involves removing your current stock, sliding the OGR unit onto the exposed buffer tube, and tightening the locking mechanism (usually an Allen set screw). No gunsmithing is required.
Why isn’t it working smoothly for me?
The most common issues are incorrect buffer tube spec (using a commercial tube), insufficient lubrication on the internal rails, or incorrect shooting technique. Ensure you’re using a firm forward hand pressure and a loose shoulder pocket to allow the rifle to slide freely.
What’s the difference between the OGR and other models?
The “OGR” (Original) typically denotes the base model with a simpler internal mechanism and polymer construction. Other models may have enhanced rails, different return spring systems, or more ergonomic shells, often at a higher price point.
Do you offer a warranty or returns?
We offer a 30-day return policy on new, unused items in original packaging. The manufacturer may have a separate warranty against defects in materials or workmanship, which we facilitate. Please see our full terms on the website.
