Upgrade your rifle with the LargeMouth FLX Magwell—a lightweight, hardware-free, and low profile flared AR15 magwell designed for faster, cleaner reloads. Made as a single solid piece, it slides onto forged milspec AR-15 lowers using a tuned friction fit: tight enough to stay locked in, easy enough to remove when needed.
No screws. No tools. No extra failure points.
Just a durable, streamlined AR15 magwell that improves reload consistency in any environment.
Why LargeMouth FLX:
One-piece, hardware-free design
Friction-fit attachment for forged mil-spec lowers
Fast, intuitive reloads with a wide flared funne
Lightweight & durable construction
Tool-free install & removal
Will fit M3 and M2 Magpul magazines.
Perfect for training, competition, or duty use.
*Please note it will be a very tight fit when installing. It will take firm pressure to install and remove the magwell. If it requires more force than you think is necessary, please reach out. Please ensure the lower you want to install it on is of milspec forged specifications. S&W sport rifles are not milspec dimensions.
