Gap between gas piston and drive block

That much gap will also quickly crack your gas block as it will get 'hammered' by the piston, rather than pushed. If you've got a side charging handle forend I'd recommend you get the V2 gas block from T&N as its just basically a hefty block of steel. I don't know what material the originals were made of (presumably some kind of aluminium alloy) but I went through one every 6-8 months

Whether its SUPPOSED to be there I couldn't say, it is there however in all of the BR99's/MKA1919's I've handled. I've also personally been through two guide rods, two bolt carriers and 5 gas blocks and they've all had a degree of wiggle in them.

Zero gap, You hear the bolt lock when the piston is pushed fully home by the drive block.
Zero braking parts. Lost count of how many 1000's of cartridges its done.
Maybe I got one that was made wrong but works right.
Can make a Utube vid to prove it, all original parts, no tinkering or mods.
