Sam,
Not sure if you saw my reply in your compliment on my SPR build or not.


I got mine from Adco. This AM it looks like Adco and EagleFirearms both have them in stock.

www.eaglefirearms.net/ARMSnumber38SPR.htm



I also received a catalog from PRI today and they list both the ARMS SPR rail for the PRI Gen I and II forearms as well as the SPR PEQ 2-3 for the Gen III model.
I have not seen any mid-length rails of this type from ARMS for the PRI tubes.

PRI also makes their own similar rail that is available in carbine, middy, and rifle lengths.

Can the ARMS SPR Swan sleeve be used on another carbon fiber free float tube? If so, what make of free float tube or outside diameter?

IIRC, the ARMS sleeve has screw positions that correspond to threaded inserts in the PRI tube. Unless the "other" tube was threaded in the exact same spot, the front mounting would iffy, at best.

Thanks, Mongo. It looks like I will be using an extended sleeve: ARMS #38 extended or super extended, with the BUIS.

You saved me a ton of money and, no doubt, headaches and an acid stomach trying to make it fit.
