KWA’s high torque gears are hardened to withstand high pressures and provide long-lasting performance from your PTS Magpul ERG Scout or CQB.


*Please note that this particular gear will not fit the new RM4 Series, including the RM4A1 and RM4 Ronins, but will fit older Magpul ERG and some earlier versions of the RM4A1. If you have an AEG 3 with an SLE, upgraded motor, and new higher speed gear setup, this gear will not fit. Please see THIS LINK for the correct part. All sales are final, so please make sure you have the right part! If you need any assistance or clarification, please give us a call at (626) 999-2795, or email us at proshop@kwausa.com.
