Firearm Parts  and  Tactical Components: Solvent Traps, Bump Stocks, Polymer 80 Kits, Glock Switches  and  Auto Sears
Across various firearm communities—both civilian and tactical—certain components stand out for what they offer in terms of performance, modularity, and maintenance. This article outlines several categories of firearm-related products commonly discussed today: Solvent Traps, Bump Stocks, Polymer 80 Kits, Glock Switches, and Auto Sears. The focus here is to provide a grounded, informative overview of these accessories and how they are typically used.

Solvent Traps
Solvent traps are simple, cylindrical attachments that screw onto the muzzle of a firearm to collect cleaning solvent. These tools make it easier to maintain rifles and pistols by keeping chemicals from splashing onto the stock, action, or floor. The internal cups or monocores inside channel the liquid into a sealed chamber. Unlike suppressors, solvent traps are closed-ended and not designed to handle pressure or pass projectiles.

Although there’s public discourse around converting solvent traps into suppressors, such modifications require federal approval and are heavily regulated. As they are sold, solvent traps remain legal and practical tools for firearm maintenance.

Variants available include:

Modular kits with aluminum, titanium, or stainless steel bodies

Threaded adapters for common barrel sizes (1/2×28, 5/8×24)

End caps, spacers, and sealed core units

Bump Stocks
A bump stock uses a firearm’s recoil to enable faster successive shots without altering the internal firing mechanism. When used with a light grip, the stock allows the rifle to slide back and forth slightly, "bumping" the trigger against a stationary finger.

These accessories remain controversial and legally restricted in some regions, but where permitted, they appeal to shooters looking for a different style of rapid fire experience without fully automatic conversions.

Bump Stock for sale options generally include:

Fixed or adjustable designs for AR-15 platforms

Easy-install brackets compatible with mil-spec lowers

High-strength polymer or reinforced composite frames

Polymer 80 Kits
Often shortened to P80, the Polymer 80 kit is a partially completed lower receiver kit that allows users to build their own firearm—most commonly a Glock-style handgun or an AR lower—from scratch. These are sometimes referred to as ghost Glocks or 80% pistols because they do not include serialized components until completed.

While many associate Polymer 80 with Glock builds, this category includes:

P80 Glock frames for 9mm and .40 builds

AR-15 80% lower receivers

Drill jigs, end mills, and parts kits for full DIY builds

Builders often choose these for the customization options they provide—grip stippling, rail variations, and color options are all within reach.

Glock Switches
A Glock switch is a small device that converts a standard Glock pistol into full-auto by altering the way the slide and trigge [https://buttonlandsears.org/product/drop-in-auto-sear-keychain/ Drop in Auto Sear] r reset. The term includes several variations, from drop-in Glock auto sears to keychain-sized switches that mimic the form factor of everyday items.

Common types of Glock switches include:

Rear plate switches

Slide-in switches

Glock switch keychain – compact and discreet design

Tool-less clip-on switches for compatible models

While installation methods vary, the general concept is the same: override the semi-automatic reset with a mechanical system that enables continuous fire. These parts are heavily regulated and only legal for specific uses under strict conditions.

Auto Sears
Auto sears—either drop-in or milled—are devices used to enable fully automatic fire in rifles or pistols. A drop-in auto sear (DIAS) is commonly used with AR-15 platforms, while others are designed for Glock handguns.

In general, an auto sear works by timing the hammer release automatically during the bolt carrier cycle. For AR builds, the DIAS sits inside the lower receiver and works in tandem with a full-auto bolt carrier group (BCG).

Buyers will often see:

Steel or titanium drop-in sears

Versions for both AR-15 and Glock platforms

Compatibility guides for full-auto configurations

Installations should be done responsibly and only where legally permitted.

Wholesale Section
Bulk Orders  and  Distributor Access
For those purchasing at scale—whether you run a tactical store, manage a training facility, or supply gun parts internationally—bulk options are available. Select categories such as Glock switches, solvent traps, and Polymer 80 kits can be ordered in wholesale quantities with discreet shipping and package consolidation available by request.

FAQ 
What is a Glock switch keychain?
It's a form of Glock auto switch designed to resemble a keychain. While small and discreet, it functions the same way when installed on a compatible model.

How does a Glock switch work?
It bypasses the semi-auto firing cycle, allowing the gun to fire continuously as long as the trigger is held.

What is a drop-in auto sear?
A small device placed inside an AR-15 lower receiver that enables automatic fire without altering the receiver’s design.

Can I install a Glock switch on a Polymer 80 Glock?
Yes, if the internal dimensions match a standard Glock, the switch will typically install the same way.

Do I need to trim or file the part before installation?
No. We ship items that are already sized and compatible with most models listed.

Do you ship worldwide?
Yes, shipping is available to most countries with discreet labeling.

Can I install an Auto Sear on my AK?
Not directly. AK platforms require their own type of sear mechanism, which differs from AR or Glock systems.
