Replacing an LR-308 Gas block

[Flydog]

Greetings! Brand new to the forum. I want to replace the factory gas block on a DPMS Oracle LR-308 (Gen 1). Does anyone know if there exists a gas block that has upper and lower picatinny rails and is adjustable? I want the rails for back-up sights and bipod mounts and it would be great if I could get one that is adjustable. I started with just looking for a drop-in replacement quad-rail forend, but can't find one. The folks at DPMS told me on the phone that no one makes one for the Gen 1 rifle.

I have never seen an adjustable gas block with both topside AND bottom picatinny. There's plenty with the top side that are adjustable. Does your rail not support a place to mount a bipod or is it a short rail?

Thanks for replying! I only have the OEM plastic forend with no way to mount a bipod on my rifle and can't find a drop-in quad rail replacement. DPMS says that they don't think anyone makes a drop-in quad rail for that rifle.

Short rail. 6 5/8 in
