Will this gas block fit on the M&P10 with everything needed for it to install a 15 inch free flow hand gaurd?

That should work fine.

Thanks for the link. I grabbed the gas block and a couple of MOE pistol grips that are on sale for $10.

Lol thats exactly what I plan on doing now

dumb question, but would this also be compatible with a M&P15 Sport? I might as well get 2 and free float that as well for these prices.

Yes, order two, they are cheap!

so my gas block came today but it didn't come with any "set screws" that's said on the site... am i missing something?

It says in two places that the block comes with set screws. I would contact Primary Arms for a remedy. Whether that is sending you set screws or a block that has them in exchange for yours that does not. Better yet, they send you a block with the screws and don't ask for the old one back.

One could check out a gunsmith or a hardware store for set screws but you paid for some already. Why pay more?

thats what I thought, just sent them a message.

Yup! Mine arrived yesterday and it should have two set screws in the bottom of the block.

damn I feel like a fool.. I just looked at the gas block again but in the day light this time with a flash light on the bottom of it and could see the set screws already in it. I guess I assumed the screws would be packaged separate or something. Oh well they haven't responded to my message yet anyway.
