H&K HK G3/91/PTR F/A Complete Training Bolt Group

Item arrived as described. Came with a bit of wear, but overall not bad for its age. These are hard to find, and I'm glad I was able to get my hands on one.

Like the title says, works exactly as expected. Fit and finish is good for a surplus item.

I have a PTR it works fine in but I also have a lucky friend with a full auto G3. We swapped out the bolts and blasted away in auto with NO problems. Probably the only thing you will notice when using this bolt is that it does not look like the bolt going fully into battery but it is.

Great addition to my ptr 91 for economical range practice. Procured some ?blue? rounds and good to go. HK phoned to ask some questions and confirm I was the purchaser. I thought that was professional service. Thank you HK parts for a cool product and your thoroughness!

Great product, and with a little modification it will work in a cetme 308 sporter. I have attached some photos of the bolt after I modified it. It works very well.

This enables the blue plastic ammo to be fired just like normal in an HK91 clone. I fed 100 rounds of the blue plastic ammunition (last affordable .308 ammo on the market in 2021) with no issues. The bolt is clearly marked (visible with the action closed) with a (Ub). That's Uebung, German for "practice", so do not use it with regular ammunition. It's a niche item, but if you fit in that niche, it's a good investment.
