As you know, one of the worst issues with shooting PCC is the inability of the plastic mags to perform consistently. Here at MBX we decided to take the problem head on and developed an extremely strong steel Glock style magazine. We improved the reduction angles and added a second stage near the top to maintain a fast and consistent “nose up presentation”. We engineered the body of the tube to correctly stack, align and feed 9mm tapered cases. The tubes have been heat treated and tempered for consistent performance and durability. The base retention lips are infinitely stronger than the plastic and will not fail when you need extreme durability.
Must have for comp shooters
I finally broke down and bought the 155mm with the 7" extension and I should've done it sooner. Yes the OEM Glock big sticks run fine but this thing is awesome and the quality is amazing. Zero feed issues at a couple local matches and a major recently. The only problem I've had is trying to drop the mag when it's loaded past maybe 30 rounds - the steel bites into the mag release really well so the button is a lot stiffer to press so I just don't use it on classifiers is all.
