  1. HK LONG GUN TALK
    Looking for experience shared by other armourers on the relation between bolt gap and function From my understanding, the MP5 has a "sweet spot" for the bolt gap at 0.25mm. HK literature specified 0.25mm to 0.50mm as the range for the bolt gap. From personal experience; Failures to Cycle...
  2. HK CLONE TALK
    Hey, all! I'm new here, although I've lurked for a few years. I recently picked up this match trigger pack from HKParts.net. Upon getting the new pack, I oiled her up and stuck it in the stock polymer PTR-91 trigger housing that came with the rifle. It was a noticeable improvement over the...

  7. HK HANDGUN TALK
    Hey folks, I've been having some problems with my USP Expert 45 ever since I've purchased it new. I always hoped that this issue was due to the gun not being broken in, but I've owned a new USP Tactical (traded in) and never had this issue before. Basically the slide will "stick" about 2-3mm...
