I just finished my 6mm creed ar. I shoot from a tripod and I have a RRS picatinny rail adapter, but I would like to find an arca rail that mounts directly to the handguard. Does anyone have a source for this? Pre reflex doesn't seem to offer anything. TIA
 
haven't seen that exactly but did see these recently:

I have one of those on my RPR but they don't have an ar10 version last time I checked.
 
@Tex_ponch

I know this is an old thread but I wanted to see if you ever came up with a solution.

I am currently building out a rifle with the PRI handguards, still unsure if I want round or the delta.

I see JP enterprises makes an ACRA rail for their MK handguard system, which may be ideal for the round PRI handguard.

There are also some flat universal ACRA rails that I think could work on a the PRI delta tubes.

I gave up and just put an arca adapter on a rail adapter on the bottom. Never found anything with the right curve.
 
The JP one looks like it has a nice curve to it. The JP forearm has an OD of 2".

I don't have a PRI forearm in front of me to measure, however their website says it has an ID of 1.9". Not sure if the JP would work or not.
