Speed Shooter Specialties "Limited" magwell offers the widest, deepest "target" for your next magazine we can offer, helping you get maximum speed. This magwell was designed for USPSA's free-wheeling "Limited" and "Open" divisions, yet it's made of aluminum, so it's very light. If you shoot USPSA, and really want a big speed-loading funnel, this part is for you. They're built to get along with our 140mm extensions, and make a fantastic pairing. If you shoot both USPSA *and* IDPA, or you'd like some weight to help suppress felt recoil, we suggest Speed Shooter Specialties' steel "ESP" variant. For maximum recoil reduction in USPSA and 3-Gun, we like the SSS brass magwell, but remember, brass magwells are not legal in IDPA.
