It doesn't say how many. I do a bunch of CQC LARPing at the range I'm at as I'm lucky have an action range that actually allows responsible fun. There's a huge difference between the handling characteristics of a 10.5" barrel over an 18.7" (WS-MCR with full length handguard and medium profile barrel), especially once you factor in weight, where the weight is and all that. I don't use brakes on SBRs and use a flash hider instead so there's actually not much difference in noise. Accuracy wise, it doesn't matter to me as the action range is 20 yards at most.
I don't do much lane shooting unless it's for zeroing of for bolt gun stuff.

So I got a lot of use and play out of an SBR
