AR experts...help me find a PIN ON low profile gas block

[jughed440]

I need one for a .75 16" Rock River heavy barrel. I'm not at all interested in clamp on, or set screw type gas blocks, but those are the only ones I can find online. The two pins on the original gas block/front sight are approx. 1.5" apart.

Any leads to a nice quality gas block would be appreciated.

I believe the pins in the original gas block are drilled through while on the barrel and catch the bottom of the barrel and then pinned to lock it in place. You are not likely to find a pre-drilled gas block that matched up with the notches already in your barrel.

Also the pins are tapered.....Can only come out one way....Why not just saw off the sight tower and use the GB that's already on the barrel?

Thanks for that info. Guess that means I'll have to do without a pin-on.

did that already... just looking around for something else.
