MKE (Makine ve Kimya Endüstrisi) AP5-SD by HiTec Arms

The MKE AP5-SD pistol represents a modern homage to one of the most iconic firearms of the 20th century, the MP5SD. This semi-automatic firearm draws inspiration from the legendary submachine gun, long favored by police and special forces across the globe for its reliability and effectiveness in close-quarters engagements.

At the heart of the AP5-SD is a 5.75-inch cold hammer-forged barrel, engineered with precision to accommodate versatile suppressor mounting options. Its 3-lug quick-attachment system and 1/2×28 RH threading provide flexibility for a wide range of suppressors, making it a practical tool for enthusiasts. Although the barrel itself is not ported, the inclusion of a removable faux suppressor enhances its authentic SD aesthetic, ensuring the firearm’s appearance remains true to its heritage while offering compatibility with 9mm silencers for those seeking quieter operation.

Manufactured in Turkey by MKE (Makina ve Kimya Endüstrisi), the AP5-SD is the product of a defense contractor with a storied history of producing firearms for military and police forces worldwide. Utilizing original HK tooling and equipment, MKE faithfully recreates the roller-delayed blowback mechanism that defined the MP5 platform in the 1970s. This innovative system, celebrated for its precision and durability, continues to set a standard for firearm engineering over five decades later.

Imported to the United States by Century Arms, the MKE AP5-SD blends modern features with the legacy of a time-tested design. Its historical lineage and exceptional craftsmanship make it a compelling choice for collectors, professionals, and shooting enthusiasts alike, reaffirming the enduring legacy of the MP5 series in contemporary firearm technology.

Don’t miss your chance to own a factory MP5SD.

Rail Installation

An MP5 can be retrofitted with an optics rail which sits above the ejection port. (Not to be confused with “claw mounts” which have a QD lever and sit way above the receiver) This optic rail is welded in place by our master gunsmiths. A slot is cut into the rail itself to keep your serial number and model exposed. Your firearm will then need to be refinished. You can opt to have it done yourself or include it in our service.

Can I ship the gun directly to HITEC ARMS?:

• Yes it’s considered gunsmithing that does not require FFL to FFL. Check your local laws to be sure.
