Unlock modern suppressor and muzzle device compatibility on your AK with the Griffin Armament Suppressor Mount Thread Adapter 1/2"x28 – Melonite QPQ Black, 24MM1228A (UPC: 791154082249). Designed specifically for 24x1.5mm AK muzzle threads, this premium adapter gives your rifle true 1/2x28 threads, opening the door to a huge range of AR-style flash hiders, brakes, compensators, and direct-thread suppressors—without having to rethread your barrel.

Turn 24x1.5mm AK Threads into 1/2x28 Suppressor-Ready Threads
Many AK platforms, especially 5.45 and 5.56 variants, ship with 24x1.5mm front sight base threads that limit your muzzle device choices. Griffin’s 24MM1228A adapter solves that: Griffin Armament+1
By converting to 1/2x28, this adapter lets you use:
AR-15 flash hiders and compensators
1/2x28 direct-thread suppressors
QD mounts and brakes that require precise timing
Perfect for shooters who want to modernize their AK with the same muzzle devices they trust on their ARs.
Not “Hardware Store Grade” – 17-4 Construction & Melonite QPQ
Griffin designed these adapters from the ground up for serious shooters, not as cheap generic bushings:
This combination ensures the adapter can withstand:
It’s built to be a permanent, duty-ready upgrade—not a temporary workaround.
Muzzle-Face Indexing for Superior Suppressor Alignment
One of the biggest challenges with surplus AKs is proper alignment for suppressors and timed muzzle devices. Unlike many cheap adapters that index off the front sight base, the Griffin 24MM1228A features a raised surface that interfaces directly with the muzzle face. Griffin Armament+2Buds Gun Shop+2
Benefits of muzzle-face indexing:
Helps ensure the adapter is square to the bore
Greatly improves theoretical alignment vs. loose detent-based devices
Reduces risk of baffle strikes and point-of-impact shifts when running a suppressor
Important: This design assumes your barrel has a clean muzzle face that’s perpendicular to the bore. On properly built rifles, this allows excellent alignment for suppressor use. Griffin Armament+2Buds Gun Shop+2
Installer-Friendly Details: 27mm Flats & Shim Step
Griffin makes installation straightforward and precise:
These features make it practical to achieve both correct torque and perfect timing on your chosen muzzle device.
Optimized for 5.45 & 5.56mm 24mm AKs
Griffin offers their 24x1.5mm adapters in both 1/2x28 and 5/8x24 versions. This 24MM1228A 1/2×28 model is specifically recommended for: Griffin Armament+1
If you’re running 7.62×39 AKs, Griffin’s 5/8×24 version is the better choice; 1/2x28 is optimized for smaller-bore calibers.
Perfect for Suppressor & Muzzle Device Upgrades
Once installed, your AK essentially behaves like a 1/2x28-threaded rifle at the muzzle, letting you:
Mount 5.56 AR-style muzzle brakes to tame recoil and muzzle rise
Use flash hiders to reduce signature in low light
Thread on direct-thread suppressors or QD mounts that demand precise alignment
It’s an ideal solution for:
Suppressor hosts where alignment and consistency are critical
AK/AR crossover builds that share the same muzzle devices
Shooters who want modern accessories without permanent gunsmithing
Just remember to verify bore alignment after installation and before live-fire suppressor use—especially if you didn’t have a gunsmith install it. Griffin Armament+2Palmetto State Armory+2
