Product Highlights:

Our AK-100 Series Combo Block is crafted to meet the demands of AK enthusiasts and professionals who prioritize quality and compatibility. Precision-machined in-house from billet 4140 alloy steel, this combo block undergoes a rigorous heat-treatment process to ensure long-lasting durability and strength. Built to match original Bulgarian AK specifications, the AK-100 Series Combo Block is designed to fit most AK platforms, including the AK-102, AK-104, and AK-105 variants. Whether you’re a seasoned gunsmith or an AK owner upgrading your rifle, this block will provide the stability and performance you need for smooth, reliable operation.

Optimized Barrel Fit: To accommodate the diverse range of AK barrels available, the barrel bore diameter of our AK-100 Series Combo Block is precisely machined to .595. This dimension is ideal for most standard and legacy barrels. For those needing a custom fit, we offer custom sizing to ensure your combo block and barrel are a perfect match. Proper fitment is critical for reliable performance, as attempting to press a block onto a mismatched barrel can cause irreversible damage to both the block and the barrel. Our focus on precision guarantees a snug, dependable fit across a wide variety of AK models.

Accurate Gas Piston Bore: Maintaining the original .552 spec for the gas piston bore, our AK-100 Series Combo Block delivers the precise gas piston performance that’s essential for optimal cycling and reliability. This ensures the part integrates seamlessly with other Bulgarian-spec components, providing you with consistent, quality performance every time you fire.

24mm Threaded for Bulgarian Specs: Our combo block is crafted specifically for Bulgarian-spec AK-102, AK-104, and AK-105 series rifles, as well as other models with a similar 90-degree gas port and barrel shoulder. With a 24mm thread, it allows for easy and secure integration with compatible rifles, making this a versatile addition to your setup.

Additional Features:

Customizable Barrel Pin: Understanding the need for flexibility, we provide the combo block’s barrel pin undrilled, allowing you to adjust for various pin sizes based on your specific requirements. We’ve included a center drill starter to simplify the drilling process. As our combo block is made from hardened steel, we recommend using a carbide end mill or a high-quality coated HSS drill bit for the best results. This attention to customization allows you to install your block confidently, knowing it’s tailored to your firearm.

Important Notes:

Due to the range of AK variations and manufacturing tolerances, slight dimensional differences (typically +/- .010) are common across AK models. For this reason, we encourage you to confirm the dimensions of your barrel and gas piston for compatibility with our combo blocks before purchasing. This will ensure a seamless fit and prevent potential installation issues.

Installation Advisory: To maximize fit and performance, this part should be installed by a skilled gunsmith experienced with the AK-47 or AK-74 platform. Correct installation ensures your AK-100 Series Combo Block integrates perfectly, maintaining both functionality and safety.
