OK fellas, I've been doing some more digging on this one. Because this can will only be used on a precision AR or possibly a bolt gun later down the road, I started looking heavily at direct thread options. The Sandman Ti is out of the running because it only comes threaded for 7.62 barrels. You know what's really dumb? They offer a 5.56 end cap, but no means to mount it on a 5.56 gun.
So, I started looking around places like snipershide to see what the precision nuts really liked. Thunderbeast has a huge following there and rightfully so. TBAC makes great cans for precision long range shooting. The other contender seemed to be the lowly SCo Harvester. Alot of guys having good results with the little can that could. Minimal POI shift and no change in group sizes.
Well, since the Harvester can be had for almost half the cost of the TBAC, it looks like I'll be picking one up next week. The modular design has the added benefit of being able to mount it on pretty much any gun that I'd need it for.
Wanna hear something else interesting? The original Harvester was built on a fully welded Octane core and can use any of the Octane mounts, including the 3 lug. Pretty neat. However, current models have a tighter bore than the originals and cannot be used with 9mm.
