EDIT to ADD:Guys, im still stumped. I need someone to email me so I can send them pics of my bolt. I figured it was Action 3 type so I disassembled my Coharie bolt and removed the wire spring retainer and rollers to install into this HK bolt and the wire spring retainer is too wide to fit the channel of my bolt. This bolt is clearly dated ID431 on the top, has what appears to be a 6G stamped on the rear locking lug that locks into the carrier to limit forward travel, also has a 0 stamped on the top of the bolt behind the roll pin hole, and is clearly a machined bolt not cast but I do believe this bolt has a F type retainer channel. Im kinda dumbfounded. ID is 1983, and the F type did not take place until 1999 from what I understand.
My bolt has a the face cuts like the second pic belowe, but the roller retainer channel is only 1/8" wide, my Coharie that uses the wire spring is at least 5/16" wide.... Anyone have an F type retainer they can measure the width of ( the narrowest width, not roller to roller ).... Can someone send me an email so I can send you pics.... LINK TO GB auction where I got the bolt. http://www.gunbroker.com/Auction/ViewItem.asp?Item=127200611 Just wondering if anyone had or could take pics of the different roller retainer plate channels in the three differrent types of MP5 bolts. Reason i ask, I picked up a ID date coded bolt which if im right is 1983. The channel is only 1/8" wide and i need to buy rollers and a retainer for it. The Cohaie bolt I have is the cast NF461 bolt and Todd claims they are type F, but the channel is wider than the ID coded HK bolt I have. From my reading the type F wasnt done until 1999, so my ID coded bolt cant be type F from what ive read, but from pics on some of the parts house websites, the channel looks like a type F. Anyone have all three types to compair? Would like pics if anyone has them, or at least measurments for each type. 1st gen –––– 2nd gen ––––Action 3 3rd gen–––– Type F |

You can rule out between Gen 1 and Action 3 by looking at the bolt face and seeing the cut. Since you know that your bolt isn't a F type it should be easy to see which one you have. If its a 1st Gen get the Retainer Plate. If its Action 3 get wire version. Check out HKparts.net
1st Gen 
Action 3 
F Bolt Looks the same as Action 3 |
