sigswiss, thanks for the information on the handguards. Any idea if the pistol grips and buttstocks interchange?

I'm wondering if anyone has successfully 3D printed magazine followers and floor plates.

Pistol grip and stock are standard 550/551/552/553. Gatewood Supply has a company that 3D printed floorplates and followers for the 550 mag. So I’m sure it can be done.

With the 751, I would like to purchase the lower picatinny rail attachment for the existing plastic forearm. I am undecided on choosing a direction, to mount a light bipod or grip / grip pod. I have plenty of time to make a decision. No rush . Intended use - light DMR.

There were a few pictures on the net of these configurations.
I'm posting my choice on the 751 thread.

I figured I might as well post a question here as well:

I have a question concerning green cheek rests if someone could possibly help.

Mr Vickers seemed to have had one in his 553R video, but where in the world could one of these be found -preferably new?

Also, I have one of the older WEZ "triple diamond" green ones, but know little to nothing about them or their years of manufacture -and Guisan's knowledge is no longer.. Any information concerning these would be greatly appreciated as well.
Here's a dusty pic!

Anyone know a reputable gunsmith to modify a 2 position gas valve into a 4 position?

Can't think of anyone with enough first hand experience to do that correctly. Is there a reason you wouldn't just buy a factory 4 pos valve?

+1. I have several that I'd like to have modified. I'd actually like to have tiny holes drilled so that I can open them up as needed.

Based on shooting my 553R, 551LB and 751 SAPR, I think that each setting allows too much gas through. I'd much rather be able to fine tune it myself. I understand that they want to make sure the valves work for everyone and pretty much all ammunition, so I'm not saying they're made wrong. It would just be nice to be able to do it right for the ammunition I'm using.
