So You Want To Buy A HK91/G3 Rifle...

[HKGuns]

Sorry haven't been an arfcom member for awhile now.

Can't blame you for that....I quit that place like a bad habit because of all the garbage that goes on over there. I think I had an account for all of 6 months.

Great information on the G3 and thanks for posting. I just bought one and have learned a lot from you in this thread.

Been a couple months, but since I'm eying an AG-3F2 clone again….

If I were to buy a Norwegian contract bolt carrier, how difficult would it be to put into a PTR-91?

I mean, I know it's stupid simple to pop a bolt out of an AR-15 BCG and throw it into another BCG, ditto the AK and the FAL. But are HK91s the same way?

You can swap bolts but you need to check bolt gap. Even if its not within spec, it can be adjusted with different size rollers and locking piece.

If I keep the same bolt but swap the carriers, do I need to check the bolt gap?

[a1fabweld]

I don't think so because the gap is determined by the pieces in the bolt head, but I would. All it takes is a feeler gage and a few minutes tops. Plus you'll have a baseline spec to compare to later if the gap changes.

Good enough. Thanks!

Next question: How does one attach and run a light with a "factory" HK91/PTR-91/G3?

[a1fabweld]

I've seen guys drill and bolt or rivet small sections of picatinny rail to the bottom or sides of the wide hand guards. You can also get railed hand guards in the aftermarket. But you can't have my KAC RAS!

[MountainRaven]

Well, the process of cloning an AG-3F2 will involve fitment of a B&T hand guard… but until that comes in, I'd like to have someway of attaching a light to the gun!

A $10 section of magpul rail outta do the trick.

I used a wooden hand guard and a section of Magpul rail. It works.
