Are you sure ? Never seen a factory short stroked one myself, all just had regular stroke and weak springs. Also what size do you understand the FAC ports to be ? I know exactly what the sub 12 rifle's ports were, but one again, not aware of two different configurations being available..
This was taken from an early review and it would seem this was the intention for sub 12fpe versions but it looks as though it was not carried out - I'll amend the article shortly.

Thanks for taking the time to let me know about this.

Thanks for spotting that - I will get them put the right way round!
