Description
The BCM Mod 3 Stock Riser Kit solves a problem plenty of AR owners run into once they mount an optic: your line of sight moves up, but your stock's cheek height doesn't. This kit gives you two friction-fit M3 marksman risers, measuring roughly .5 inch and .8 inch, so you can raise your head to the glass instead of craning your neck down to it. Both risers are built from polymer and aluminum with a clean black finish, and they're designed to interface directly with the Mod 3 stock.
Six Mounting Positions on the Mod 3 Riser Kit
Where this kit earns its keep is the adjustability. Each riser can be mounted in six different positions and oriented either forward or reverse, which gives you a real range of cheek height and eye relief combinations to work with. Whether you're running a red dot, a low-power variable optic, or a passive night vision setup, you can fine-tune where your face sits until the sight picture drops in fast and repeats every time you shoulder the gun. That kind of consistency is the whole point of a good cheek weld.
Why the BCM M3 Marksman Risers Work
These aren't clunky bolt-on cheek pads. The friction-fit design keeps things low-profile and snag-free, staying true to the minimalist character of the Mod 3 platform. They add height where you need it without bulking up the stock or adding meaningful weight, and they're made in the USA to the same standards BCM builds the rest of their gear to.
One thing worth knowing before you order: this is the riser kit only. The BCM Mod 3 stock itself is sold separately, so make sure you've got one on your rifle or in your cart. If you already run the Mod 3 and want a cleaner sight picture with your optic, this is the piece that gets you there.

Frequently Asked Questions
Does the BCM Mod 3 Stock Riser Kit include the stock?
No, this kit is the risers only. The two M3 marksman risers are designed to interface with the BCM Mod 3 stock, which is sold separately. Make sure you already have a Mod 3 on your rifle or add one before you head to the range.
How do the two risers differ in height?
The kit comes with two friction-fit risers, one measuring about 0.5 inch and one about 0.8 inch. You pick the height that lines your eye up with your optic. Combined with the forward and reverse orientation, you get a solid range of cheek height options.
What optics work best with the Mod 3 riser kit?
The risers are built to give you a consistent cheek weld with electro-optics, low-power variable optics, and passive night vision setups. Anything that sits higher than iron sights benefits from raising your cheek position. The six mounting positions let you tune the fit to your specific optic and shooting style.
Are the risers easy to install?
Yes, the friction-fit design means they seat onto the Mod 3 stock without much fuss. You can experiment with the different positions and orientations to find your preferred sight picture, then leave them set where they feel right. No special tools are needed to get them dialed in.
