I just received my ambi mag release for my XCR-L today and now have a fitting question = it didn't come with any info.
I removed the old mag release by pushing in the mag release button and unscrewing the left side.
I screwed the new release in but it won't slip into place in the loweer receiver I see the front of the old lever is square and the new lever is rounded.
Do I need to grind away on my lower receiver to get this to fit properly into the receiver or grind the rounded part of the new release square?
Help...
