Product Overview
The proven Slip Fit Magwell (SFM) for AR standard forged lowers
Driven Arms' tried and true attachment method, co-developed with Darq Industries, embraces simplicity – its ultra-simple three-piece construction offers a secure and reliable fit, while also keeping the overall weight low, right at .55 oz, making it nearly invisible on your weapon system until you utilize the 150%+ increased funnel size.
All function, no fluff, everything an AR magwell flare should be.
Made for AR-15 forged and milspec lowers.
FEATURES
- Fits most AR15 forged and milspec lowers (e.g., Daniel Defense, Geissele, BCM, PSA, Anderson, Spikes, Aero, HK MR556 A4)
- Low profile design, free of snag points, offers unobstructed manual of arms
- Durable single-piece nylon construction
- Simplified hardware reduces potential failure points to effectively none
- Ultralight construction: ~ 0.55 oz including hardware
Compatible with: Daniel Defense, BCM, PSA, Spikes, Anderson, Aero Precision (AR-15 & X15), Centurion, Diamondback, HK MR556 A4, Noveske Chainsaw, and many more.
For Geissele owners, please note – this fits the forged models only, including the Super Duty Mod 1, however the 2026 and newer Super Duty Mod 1 A utilizes a proprietary lower, and a new model is in the works for this, with a targeted Q3 2026 release.
