Ok, It is official from me now - - +1 on John Thomas @ Retro Arms Works !!! :)
Fit & finish are superb; From my trained eye I can tell that the FSB has been
mounted perfectly in line with the barrel extension indexing pin & where
the rear sight will be when the carry handle is mounted. Perfect work,
2 day turnaround, & excellent protective wrapping on the return shipping !!! :)
Wholeheartedly recommended by me, and I will not hesitate to use him again :)
Thanks John !! S!
