    BA Hanson gas block pinning

    In this video it is stated that with the coil pin that they use there is play in the gas block even after the pin is installed. Is it just me or does that sound like shitty useless pinning for a gas block, and all that actually holds it in alignment are the un-dimpled set screws? This is an older video so maybe things have changed.

    I have a couple, never used the screws, and the pin was more than enough .

    No slop.

    No play after pinning? How old are your barrels?

    I am not sure. But I would probably say a couple of years.

    Maybe something changed??

    I’ve had two of their pinned/set screw gas block barrels. A 300blk and now recently one for my Mk12-ish build with the gas block exposed. Both have been solid with no movement.

    I think he got tongue tied between set screws and the pin.

    I have seen play between a coil pinned gas block, yes. It was not BA but Faxon (their special run "drilled for cross pin" barrels).

    Said barrels are also undimpled too so I was able to used a plastic mallet and whack the gas block and have it rotate slightly, this was fixed by replacing the short little coil pin with a longer dowel pin of the same diameter.

    I haven't seen a BA barrel that wasn't dimpled for the set screws (though I know they exist or did at one time) but the few dimpled only BA barrels I've used have been rock solid, I could imagine that with the cross pin there would be virtually no way for the gas block to move.

    BA Hanson gas block pinning

    I have a 14.5" Hanson, very recent purchase. No play at all in factory pinned GB.

    I have no slop at all with my 8 year old 5.56 and none with my 6 year old 6.5 Creed (not Hanson but they pinned the Gas Block for me)
    In no way do I make any money from anyone related to the firearms industry.
