ar 15 gasblock with valve

brecht

Is there a gasblock for the Ar 15 with a shutoff valve like there is with some SKS? This would allow the switch from semiautomatic to straightpull action and would be useful in a suppressed 300 blackout.

There is indeed such a device, or at least close to it:

My piston upper does that as well.

brecht,

The one I use is made by Noveske:

It is 3-position:

ON, OFF, SUPPRESSED

The gas port will require tuning to run open and suppressed.

Best.

thanks guys.
I think the noveske with a LAR OPS 4 side charging upper in 300 blackout would make a great combination.
