Other way round, SRC have improved tremendously in quality over the last couple of years and are pretty solid builds now. full aluminium, not pot metal. 8mm bearings and double O ringed everything. Only issue with the Mamba EBB's is the total lack of a manual for them and they dont strip down as other M4's. I have 2 SRC G36 Gen 3's and a Mamba S Gen 3 EBB, amongst many rifs, all are good
JustBB's are the UK SRC importer, they have a deal to rebrand them as their own brand Bulldog. They are the local shop to me and yes, they do cater for the 5 year old Blue gun brigade but they are actually very helpful and do have a good proper RIF selection. Don't understand some of the anti feeling for them
RC1124, did you get the correct manual with your Mamba?
