Purebred 13” MLOK Handguard

$173.99

The Rosco Mfg. Purebred 13” Mlok handguard is designed to create a free-floated mounting platform to provide the shooter with a solid base for Magpul M-LOK compatible components and accessories. By using a free-floated design the accuracy capabilities of the upper receiver are enhanced and create repeatable results on target.

Optimal length handguard for barrels that measure 13.7” to 16” but will also work perfectly with shorter barrels if an enclosed muzzle device is used to extend length (I.E. SLR Rifleworks “Synergy Linear Comp”). We recommend installation of this item be conducted by a professional gunsmith.

    It is a beautiful piece of work, just need for the sauce packs to be available so I can install it. 🙂

    This rail is the BEST option for 13.7″ barrels. I bought this rail after buying a STNGR HWK 13.5″ and a Strike 13.5″ rail. My Deadair Sandman suppressor would not mount because the rails are too long and are not wide enough. With the Rosco rail, everything fits like a glove. Gas block is easy to access and control, suppressor mounts with just enough space between it and the front of the rail, and the rail is easy to remove if needed.

    This is one of the finest quality handguards I’ve had in my hands, and also perhaps the lightest! Excellent machining and finish. I cannot wait to install this along with my 14.5″ sauce pack! The video installation guide available on YouTube is very clearly presented without any skipped steps. Thanks Rosco!

    This handgaurd is one of my new favorites, it’s the same as the one made by ADM. Super nice fit and finish.

    Great handguard! I just built a 13.7 with a rosco sauce pack. It started with a Bcm rail that ended up being too long so I returned it. I didn’t realize at the time that rosco made handguards until I saw a post on Instagram. Thankfully they were in stock and on sale for the 4th of July. It seems like solid construction and to be honest I prefer this build over my geissele urgi 14.5. The rail is lighter and the gas port is perfect in the 13.7. It doesn’t like cheap steel case but is smooth as butter with brass 223 and 556 with the A5H2 buffer.
