I've so far had about 1000rds thru your linear comp on my pdw (mix of MFS & M855/193) . I really like its smaller diameter profile (not like the pig). It definitely mitigates alot of the sound and felt recoil that the A2 was not good at for a 7.5". One thing though, it does have a lot of flash. Are there plans to also include flash suppression for night shoots?
I do have FB video but I don't know how to post it.
PS, I did email an official receipt from OST to get the rebate (Order Number : 12359). Did you receive it?
