BLACKHORN Division / Custom Builds

Start Your Custom BLACKHORN Build

Not every support weapon fits a fixed configuration. If you're starting with an M240, Mk.43/M60, PKM/PKP, or another platform that needs more than a list of parts, tell us what you're working with and what you need it to do. We'll review the project, help sort out the right configuration, and treat the gun as one complete system.

The Process

How a Custom Build Starts

We need enough information to understand the platform and your actual goal before recommending parts or quoting the job.

01 / SEND THE DETAILS

Tell Us What You Have

Give us the exact platform, manufacturer, current configuration, and what you want to improve.

02 / PROJECT REVIEW

We Check the Build

We'll review fitment, parts availability, AEG/HPA options, feeding, and whether the goal makes sense for the platform.

03 / LOCK IT IN

Confirm the Configuration

We'll work through scope, pricing, shipping, and the next steps with you before anything moves forward.

04 / BUILD & TEST

Built as a Complete System

Once approved, the platform is assembled, tuned, and tested in-house. Build and tuning information are included.

Custom Platforms

What We Can Build Around

These platforms are handled individually because the correct configuration depends heavily on the base gun, intended role, and customer's requirements.

Full-size support weapon

M240

Weight reduction, external configuration, AEG/HPA setup, feed systems, and Bull Craft components selected around the role you need it to fill.

Classic support platform

MK.43 / M60

Internal performance, handling, feeding, and external changes planned together instead of installed as unrelated upgrades.

Purpose-built configuration

PKM / PKP

Weight and balance, feed reliability, HPA conversion, and Bull Craft components brought together around the customer's intended use.

Have something else in mind? Send the exact manufacturer, model, and goal. We'll tell you whether the project makes sense before you spend money.

Before You Submit

What to Have Ready

You don't need every answer figured out. These details simply give us a useful place to start.

  • The exact platform and manufacturer, if known
  • Whether you already own the donor platform
  • Your field's energy limit and preferred BB weight
  • Whether you prefer AEG, HPA, or need guidance
  • The main problem you want the build to solve
  • Your working budget and any real deadline or event

Custom Build Request

Tell Us About the Build

The more specific you are, the more useful our first reply can be. If you don't know an answer yet, select “Not sure” and we'll work through it with you.

Include your field limit, preferred BB weight, or other measurable goals if known.

Submitting this form is not an order or final quote. It gives us enough information to review the project and determine the next step.

Common Questions

Before We Get Started

A custom request starts a conversation. It doesn't lock you into a configuration or create a charge.

Do I need to already own the platform?

Not always. Some projects can begin with a platform sourced by Bull Craft, while others are best handled as customer-supplied builds. Select your starting point in the form and we'll confirm what's practical.

Can you build both AEG and HPA platforms?

Yes. The right power system depends on the platform, intended use, performance target, and budget. If you're open to either, we'll help sort out the tradeoffs.

Can the build be tuned to my field limit?

We can build toward a requested energy limit and BB weight. The final setup depends on the platform, barrel, engine or internal parts, and the rules where you intend to use it.

Can I send photos with the request?

The initial form doesn't accept attachments. Once we've reviewed the request, we may ask for photos of the base gun or specific areas that affect fitment and configuration.

Is the form a final quote?

No. The form gives us the information needed to review the project. Configuration, pricing, shipping, and the next steps are confirmed directly with you before the build moves forward.
