Up for sale is a new MAD DOG US made improved MP5 9mm complete drop in bolt head. This unit work on all MP5 9mm variants.This was a HK design that was developed in the 1980's for production MP5 units, but was dropped in favor for the development/production of the UMP series. These are very well made and function well. The weak point on the standard HK bolt head is the extractor spring that needs to be replaced after a few thousand rounds. The MADDOG unit uses an extractor coil spring instead of the straight wire design. I have these install on my various MP5 clones with excellent results, MP5SD, MP5K, Full sized and reverse stretch MP5's. Pics below show a comparison of the MADDOG unit vs a RCM made stock replacement unit. $249, $9 priority mail shipping.
