fx impact new cf bottle

"sniperlabyo"Easy mod, I forgot I think filing down less than 1/8” to clear bottle, you can remove lower rail for easy filing / grinding / sanding and polishing and yes it’s the only obstruction that prevent the bottle from screwing on flush. 

Thanks, Ernest . . . seems easy enough to do.

Did you say that you got the valves for around $70? The link you provided lists them at around $94 right now so did the price go up or do they go on sale or ??? Thx
 
You can email them, if you buy more then one the price is lower, if just wanting one AOA sell them for $108 with shipping the last time I purchased. 

Look like the same MFR made them.

wish they cost $50 to be fair 

if you have two AG that can used the same bottle and wanting to carry a small fill bottle like this--they also sell, then it's worth buying more than one valve.

note: if competing it's best to change bottle then refilling the bottle its quicker and the air temp on the spare bottle is stabilized/cooled to space temp.
