Not really sure where to post this.....
Hey guys. So, I'm currently getting ready to start in on my first HK build. A HK53.
I picked up the barreled front end and a BCG from Apex awhile back when they were on sale. First off, these are from Demilled Century C93 Pistols. So they're not the best. the BCG is a modified HK33 carrier so it has the built in buffer.
NOW, I have a couple questions.
I picked up a HK33 cocking tube support for about 30 bucks with a g3 flash hider.
1: What is the correct length I need to cut off the back end of it to work?
2: Is there a specific way to weld on the rear stock pin bushing onto the receiver?
3: where do I need to cut the receiver to get the correct spacing for the cocking tube?
I currently have a flat bending jig I got second hand and from what I can tell, I have everything except the larger (starting?) rod. the jig is the one that is double sided. one end has a smaller opening than the other. it also came with no instruction, but I've pretty much been able to figure it out via youtube.
4: Would I be G.T.G. with just using the main pressing rod to bend the flat?
5: Would I be okay with cutting the tab off the buffer in order to use a SB tac side folding brace?
I Already have a Flat (hkparts.net) that I'm going to bend and I've already demilled the front end so I now have a barreled and populated front trunnion and I was able to save the cocking tube as well.
I would start with known quality components. Scrap the century front end. Use RCM barrel, bolt group instead. Find a german trunion or use RCM. Or consider buying a MKE AT43 pistol, send to TPM and have it converted to 53.
Well, I already have the parts and I've already committed to this project. So, it's going to get built.
cool story, bro, care to tell it again?
@jik294 the larger bar is to fix out of spec G3 flats. You probably wont need it.

caf82313, Yeah I know. I've built several AR's, messed a little with AK's and HK's. but I've never groundup built an HK, so I decided I wanted to learn something new. It's something I have extreme confidence in doing.
There is surprisingly little I've found about building an HK53. So I've been taking a lot of pictures throughout the process and plan on posting everything when I get done.
