Alex Pro Firearms 6.5Gren Pistol 2.0 14.5 Blk Mlok
The Alex Pro Firearms 6.5 Grendel pistol is a modern, semi-auto AR-platform pistol built on a billet receiver and purpose-designed for shooters who want precision rifle performance in a compact, maneuverable package. At 14.5 inches, the 4150CM nitride-coated barrel strikes a practical balance between velocity and portability—ideal for hunting, defense, or the range. The 6.5 Grendel cartridge delivers impressive ballistic efficiency in a smaller form factor than standard rifle builds, making this pistol a serious tool for those who appreciate uncommon calibers and refined engineering.
Every component here reflects APF's focus on reliability and shootability. The nitride-finished bolt carrier group, adjustable gas block, and mil-spec ambidextrous controls ensure consistent operation and ergonomic access whether you're right- or left-handed. The 1:8 twist barrel is optimized for 6.5 Grendel, stabilizing a wide range of bullet weights. Trigger discipline starts with the factory 4.5 lb. drop-in trigger—crisp enough for precision, predictable enough for dynamic work. The SBA3 pistol brace and Magpul MOE grip provide a solid, repeatable platform, while the 13-inch M-Lok handguard gives you real estate for mounting optics, lights, or other modern accessories.
This is a rifle-caliber pistol that respects its lineage. The billet aluminum construction, Cerakote finish in black, and attention to gas system tuning mean you're holding equipment designed for serious use. Whether you're building a truck gun, home-defense backup, or exploring what 6.5 Grendel can do in a compact format, the Alex Pro Firearms 6.5 Grendel Pistol 2.0 delivers versatility without compromise.

Frequently Asked Questions
What optics can I mount on this 6.5 Grendel pistol?
The flat-top billet receiver includes a Picatinny rail for optics mounting. The 13" M-Lok handguard also accepts M-Lok accessories. You'll want to choose an optic and mounting solution that work for your intended use—compact red dots or prism scopes are popular for pistol builds. No iron sights are included, so an optic or backup sight system is recommended.
Is this pistol compatible with standard AR magazines?
The 6.5 Grendel caliber uses its own magazine platform—6.5 Grendel magazines are not interchangeable with standard 5.56 or .308 AR mags. Make sure to source proper 6.5 Grendel magazines for reliable feeding and function.
Can I add a suppressor or other muzzle devices?
The barrel has a standard threaded muzzle suitable for suppressors and other muzzle devices. The adjustable gas block will help you tune the gun's performance if you add a suppressor, which can affect cycling and reliability.
What's the advantage of the adjustable gas block on this 6.5 Grendel pistol?
The adjustable gas block lets you fine-tune gas system pressure to your specific ammunition, load, and setup. This is especially useful in short-barreled pistol builds, where you may need to dial in the perfect balance between reliable cycling and managing recoil impulse. It also helps if you plan to run a suppressor in the future.
