You're not bulletproof...

Ruger 10/22 Archangel Marauder

Can’t afford to do an H&K SL8-to-G36 conversion? Cheapest alternative would be this chassis system for the venerable Ruger 10/22 rifle. It mimics the G36, and from a distance it would look like the real thing, although the solid magazine would be a giveaway since real G36 mags are transparent. Although it looks like a high capacity magazine, the one pictured is actually a 10-rounder. You can still uses normal high capacity Ruger 10/22 magazines, it’ll just look a bit weird.
