Darq Industries Slip Fit Magwell (SFM) for Standard Forged M4/AR15 Receiver (R)

Darq Industries was formerly known as Goonin Gear.
This model of the SFM™ fits standard forged M4/AR15 lower receivers. It will not fit proprietary lowers with larger magwells, such as the Aero E1, Radian, etc.


The SFM™ (patent pending) was designed with a minimalist approach to increase funnel size without compromising speed of other actions.

#1: Efficiency
The SFM™ allows for improved reloads while using Night Vision or when close focus is impaired. Night Vision has a fixed focal plane, meaning if objects in the distance are in focus those that are up close will not be. Having a larger funnel size is hugely beneficial here as it compensates for margin of error in insertion due to lost close focus. Thinking a step further; having a large funnel is great, but the larger it is the more potential it has to be counter productive to a smooth reload. It’s not just about insertion. If the funnel is too large it can impede your ability to hit the bolt catch. Not everyone reloads the same way, but many slide their hand up after inserting a mag. Having a funnel too large impedes your ability to slide your hand up smoothly, slowing down hitting the bolt catch. Or potentially blocking your thumb from pressing inward as freely. We went through many size and shape iterations in an effort to find what we feel is an optimal size. The SFM™ has a 170% increase in funnel size over stock. There is also a slight taper towards the rear of the SFM allowing just a bit more freedom to slide your hand up for bolt catch engagement or pressing your thumb in.

#2: Simplicity
The Patent Pending Slip Fit™ attachment method is simple, lightweight, and secure. Using a single 4-40 socket head screw, weight is kept to an absolute minimum. The screw doesn’t require loctite as the way it attaches imparts positive tension onto itself, acting as a lock washer. However, if you are someone who loctites everything a single drop of blue will be more than enough. The SFM™ naturally grips the stock lip and will not come off unless forcibly peeled away. Overall it’s a simple yet very secure design.
