| Anyone build one of these? If so how hard is it to do? Where is a good place to find parts and info on them? Thanks |

If you're building a CETME/HK type gun from a receiver 'flat' and parts kit, it isn't something you can do on the kitchen table. It requires bending the flat into shape with the help of a jig, then TIG welding it while keeping it straight, then welding the trunion to the receiver, then pressing in the barrel and making sure the bolt gap correct. |
| Thanks for the info I do have plenty welding and fab experiance (I am a maintence person / welder) and was thinking of doing one from a receiver that is cast. How hard is to assemble from the cast receiver? I do have some gunsmithing abilities, I built a .257 on a mauser action, customised a 1911 and built a couple AR15s but wanted to check with people that have built CETMEs before jumping into it. Thanks |

Cast receivers add another twist. Since it's not possible to weld steel to aluminum, the cast receivered guns had the trunnions simply pinned and glued into place. This caused a rash of problems and is one of the main reasons they (cast receivers) are looked down on. IMO you would be far better off to get a finished PTR receiver from HKparts.net and go from there. http://www.hkparts.net/91.htm Parts kits have pretty much dried up and are at a premium right now. A complete kit in nice condition is going to run you approx $600-700+ |
