Looking for a well versed and extremely knowledgeable HK roller lock smith to help me out with some future modifications, builds, conversions and parts upgrades. I'm located here in NW GA. However, I don't mind traveling the distance to the right individual. So... Who's the king ding a ling on ODT with roller lock guns? I've met a few other roller lock guys here or many of them wanting roller lock style guns. Thanks ODT brothers! I pride myself on having a wealth on knowledge, but again by no means am I claiming to be a know it all. Thanks for your help in advance. Respectfully- jlangrill454lsx
