DPMS format Forearm/Rail question

[Venom_6]

FNG here.

New to the LR308 scene so please excuse the question, but would there be any fitting issues putting an Armalite railed forearm (AR10 NM forearm) on a SI Defense barreled upper? 

Thanks,

V6

Ok, thanks.  Is there any rail similar for the dpms format other than the KAC ?

There's a thread on this sight some where ,that talks abut rails .

Just about all the hand guard manufacturers make there rails in both DPMS & Armlite configurations , some don't ,but most do.

I kinda like to the Vtac , myself , but look up DD ,PRI, & theres a bunch of others.
