Description
The Ultimate Compact 9mm SBR
When Breacher’s Custom Guns puts their name on something, you know it’s built right. The AP5SD-K SBR takes the proven roller-delayed blowback system that’s been trusted for decades and packages it into one of the most capable compact firearms available today. This isn’t just another short-barreled rifle—it’s a purpose-built tool that delivers exceptional performance in a surprisingly manageable package.
What Makes This SBR Special
What sets the AP5SD-K apart from other 9mm SBRs is how it manages recoil. The roller-delayed blowback action isn’t just a marketing term—it’s a mechanical advantage that makes this rifle shoot smoother than any direct blowback 9mm you’ve handled. That 5-inch barrel might look short, but paired with the integrated suppressor, you’re getting ballistics that rival much longer barrels while maintaining a compact overall length. The weight distribution is perfect too—at 7 pounds 14 ounces, it feels substantial without being heavy, and that balance makes it point naturally whether you’re shooting from the shoulder or using optics.
Florida-Friendly Firepower
Here in Florida, we appreciate gear that works in our environment. The AP5SD-K’s corrosion-resistant finish handles our humidity without complaint, and the compact size makes it ideal for vehicle storage or home defense scenarios where space matters. Whether you’re heading to one of Central Florida’s indoor ranges or keeping it ready for home protection, this SBR delivers the performance Florida gun owners expect. At Sunshine Gun Shop, we’ve seen how well these perform in local conditions, and we’re confident you’ll appreciate the quality.

Owning an NFA item in Florida is straightforward when you work with experienced dealers. We’ll guide you through the Form 4 process from start to finish, making sure all your paperwork is correct before submission. The wait times are what they are, but having a quality SBR like the AP5SD-K at the end is worth it. This rifle isn’t just a range toy—it’s a serious piece of equipment that performs when it counts, and we’re here to make sure you get it into your hands properly.
NFA-Regulated Firearm — ATF Form 4 Required
This is a short-barreled rifle (SBR) regulated under the National Firearms Act. Purchase requires an ATF Form 4 transfer, a $200 federal tax stamp, and approximately 30–120 days of ATF processing (eForm 4 is typically faster than paper). The firearm ships to a licensed FFL/SOT dealer of your choice; you take possession only after ATF approval.
SBRs are currently legal to own in most U.S. states. They remain prohibited or restricted for civilian possession in California, New York, New Jersey, Washington D.C., Hawaii, Iowa, Rhode Island, and Washington State. Check your state and local law before ordering. By placing an order you affirm that possession is lawful in your jurisdiction and that you are 21+ with no prohibiting factors under 18 U.S.C. §922(g).

Frequently Asked Questions
What's the NFA process for buying this SBR?
You'll need to complete a Form 4 transfer through your local FFL. We handle the paperwork on our end and ship to your chosen dealer. Once approved, you pick it up from them. The process includes fingerprint cards and a passport photo.
How long does the NFA approval take?
Current wait times for Form 4 approvals average 6-9 months for individual transfers. Trust transfers through an LLC or corporation can sometimes process faster. We submit everything electronically to speed up the process.
Do you ship to Florida FFLs?
Yes, we ship to any licensed Florida FFL dealer. You choose the dealer during checkout, and we coordinate the transfer directly with them. Make sure your chosen dealer accepts NFA items before ordering.
Why choose 9mm for an SBR?
9mm in an SBR platform gives you manageable recoil, affordable ammunition, and excellent performance with subsonic rounds through the integrated suppressor. It's ideal for home defense and range use where you want effective power without excessive noise or recoil.

This thing shoots smoother than any 9mm I’ve owned. The suppressor really works well with the short barrel. Perfect for my boat and truck without taking up much space.
Sarah L. (verified owner) –
Worth the NFA wait. The build quality is excellent, and it handles Florida humidity better than my other guns. Only wish it came with more magazines.
Carlos M. (verified owner) –
Bought this for home defense and it’s perfect. Compact enough for tight spaces but still accurate at indoor range distances. The roller-delayed action makes follow-up shots easy.
