I tried doing a search and nothing turned up.  Does anyone have a list of SPR specific parts i would need to build one.  This will be my second build, and i really like the SPR's.

I want to build one before i get deployed to PATFOR SWA (USCG).  any help would be greatly appreciated.

Thanks
Eric

Offhand, it's getting so there are as many SPR variants lately as there are makers of AR's. The SPR started out (best as I can remember) with a WOA Douglas 18" bbl (ADCO firearms has these in stock last I checked), PRi forend/gas block w/BUIS, Harris bipod and I believe the original scope was a Leupold, but I don't recall the exact model. The muzzle brake was a proprietary design by OPS, Inc. The brake was a 2-port design with a collar which could be screwed off the brake for mounting the "special" OPS Inc suppressor which came as part of the overall SPR package supplied to the military.

Wes at MSTN has all the exact specs of the original and its many variants...such as the Marine variant which useda KAC M5 RAS forend. Shoot him an email and he'll be able to hook you up.

Thanks for your help.  I really appreciate it

Have you read the Wikipedia article?

There are two main variants that I'm aware of, the Mark 12 Mod 0:

by MSTN

by ADCO

and the Mark 12 Mod 1:

by MSTN?

Hope that helps.
