-Introducing Patriot CNC's +4 Extension for the Springfield Echelon. The +4 extension was designed for someone looking to maximize their magazine capacity. These extensions are not USPSA approved, but are only slightly larger than the +3 extensions.
-These +4 extensions require no modification to your existing magazine. You simply remove your factory baseplate or extension, and install our extension in its place. There is no spring replacement required!
The extensions are made to fit the factory OEM 17rd magazines. These will not work with the 15rd or 10 rd magazines.

+4 echelon baseplate
Well built, great design, Phenomenal finish. Extremely easy to install, disassemble for cleaning. Highly recommend this baseplate. Oh and it looks Bad@$$ with their Echelon magwell aswell. A++++ dont hesitate to snag one.

Top teir will only run these exclusively now!!!
What a great company cannot say enough good stuff put in a couple orders. First order the pin and set screw that retains the base plate to the magazine was missing on one of the five base plates that I bought contacted customer service. They immediately addressed it and got the issue. Taken care of immediately ordered five more and I'm about to order five or 10 more not only do they look great but they function great, and are a nice solid addition to any build
