I owned all the early camo HK 93 and 91's. The paint fell of the plastic, when you looked at them. Especially, that green on yellow. The latest desert is horrible. Tropentarn...yuk. I did change a bunch of parts to make it better....
Up to you, but I purchased 2 C&P MP5 lowers from HKParts, in the last 2 weeks. Both fit perfectly for my applications. Your results
may vary. I don't have any issues with them.
