    Understood, thanks! Any thoughts on the #17 locking piece?

    I'm somewhat confused. I also "have an old Fleming HK91/G3 conversion". Other than replacing the welded up bolt carrier with a surplus G3 bolt carrier, just because, it has never needed anything whatsoever. Mine is a RR PP weapon and works perfectly. It loves to eat the blue DAG training ammo using the correct training bolt from Dan's Ammo. This is one of the funnest configurations out there. Plus, it's cheap to shoot.

    If I was going to shoot it I would do the following.

    Discover if it is a RR or a sear that you could “unmarry” from the receiver. Google is your friend, a lot of previous discussions on this topic. My guess is you have a “married sear”. If so “unmarry” and start buying all types of Roller Locks to play with.

    Replace the BC with a tungsten, plenty of them for sale. Then check your bolt gap.

    Replace the stock with a HK 21 and Rubber Pad. This makes shooting a 7.62 a lot more fun.

    Replace the buffer in stock with a new heavy two stage.

    If the rifle is a RR send it to TPM and have them make it a G3k. If you are able to “unmarry” do a Form 1 to SBR it then send it off to shorten. The G3 is terrible unbalanced and heavy platform. If they would have started making them as a G3k in the let 60’s the rifle might be more popular.

    1. This is a sear gun. Not in the cards at this time to "unmarry" and share around with other platforms. Might do down the road.
    2. Will do. Now officially looking for a tungsten BC.
    3. Stock is replaced already with an SG-1 stock containing a G-3 Heavy buffer.
    4. Likelier to send off to get a HK-11 barrel if they still exist. I appreciate your position on the G3K and were this a duty rifle I might agree, but it fills the niche of squad auto so in this case (within reason) heavier is better.

    Would that mine was trouble free as yours was. Mine has had the trigger pack completely replaced. The bolt work just looks shoddy and there are wear patterns developing due to the shoddy workmanship. So while it technically may not be broken, neither is it remotely optimized for its intended purpose. Thus the move to finish upgrading before running rounds down range again.

    If this converted HK91 / G3 is in original configuration and removing the sear produces no prohibited configuration...it's always been my understanding that there's no need to "unmarry" from the host. Remove the sear and all you have is a HK91...not a prohibited configuration. Were it sitting in a MP5, MP5k, 53, etc...then yes, you'd need to SBR the original host first. With your configuration...move it to any other hosts at your leisure IMO.

    I forgot to mention I use the 17 LP on my 21’s and yes they do make a difference. I also use one on a MSGk with SF suppressor and it works great.
