I've had a few experiences with Rim Country MFG. They are the real deal. They are a full time metal working/manufacturing firm. Mike Z. is good to go and will do his best to take care of your order.
Their MP5 trunions are excellent as well as their barrels. A friend of mine uses their complete bolt carrier which was originally going to be put away as a spare.
If you look in the gallery section under "SP89 rebuild" you'll see a Rim Country MP5k barrel that I installed on an SP89. It's nice to see a company who has stepped up and making parts for the end users. Their prices are good as well as their products.
