The proven Slip Fit Magwell (SFM™) for AR standard forged lowers
Our tried and true attachment method, co-developed with Darq Industries, embraces simplicity, allowing our magwells to be comprised of only three pieces – the polymer “funnel”/magwell itself, one 4-40 socket head screw, and one threaded insert. This package offers a secure and reliable fit, while also keeping the overall weight right at .55 oz, making it nearly invisible on your weapon system until you utilize the 150%+ increased funnel size – all function, no fluff.
*works with most standard forged sets. If yours isn’t a standard forged model it likely will not work. We have personally tested fitment on Daniel Defense, Geissele Super Duty, BCM, Spikes, Anderson, Aero Precision AR15 and X15, Centurion, and Diamondback lowers, with end users running them on numerous additional platforms as well. Due to tolerance stacking across batches of magwells, and differing manufacturer specs, some fitments may be tighter or looser than others – if you encounter any trouble when installing your SFM™ please contact us for assistance.

For Aero M4E1/BA Enhanced, please use this variant. For Radian ADAC, please use this one. ADM, Griffin, LMT and other models are in the works, so keep an eye out if you run their lowers!
Please Note:
Due to the efficient attachment method, minimal torque is needed when tightening the screw. Simply tighten the screw until the split section begins to touch, then just shy of a 1/2 turn of the screw for final torquing. DO NOT OVERTORQUE

I just ordered / received two old logo “blem” magwells and the fit, finish, and quality is amazing. You can’t tell it’s “blemished”. Put them on a basic Del-Ton and Daniel Defense lower and they fit both perfectly. Customer service is also amazing with this company, had an issue with a 2nd order and they were more than willing to help me out. Will definitely buy more and recommend!

EASY install and such a clean looking product. I am glad I waited for it to come back into stock and to get the DAC logo on it. Now the dilemma of determining with grip to pick!

These are a great balance between weight, size, simplicity and overall increase in funnel size. Very easy to install and look fantastic.

I was worried that this would not fit my mil spec lower since it is a goofy budget model, but it squeezed on nicely. <3
