Here is a Colt type that would work, I think. Anyway the clamp-on type by S&W looks good as well.

jtallen83,
Thanks for looking. The journal is only 1.1 inches, so a clamp-on 2 groove picatinny rail gas block would be ideal. I believe Colt mad one also. The others I have seen so far, are all pretty long for that journal.
Hi everybody ! New to this site but not to AR's.
Does anybody know who makes the picatinny rail gas block with only two rail grooves for the S&W MP10 rifle ?
S&W won't tell me so I am looking for someone who knows OR a take off somebody doesn't need anymore.
Any help or information much appreciated.
Thanks for reading
