AW Custom 50 Round Gas Magazine for VX Series SAI BLU GBB Pistols (Model: MOS)

"No problems at all. Has a good and consistent seal.

"This was a great purchase. $49 bucks!!!! When most GBB extended mags are ridiculous in price. Some SMG's run $70-80 bucks!!!!! Just a shame, shamefully these company's are charging ridiculous pricings.

However AW seems to be reasonable. Thanks AW!!!

"It is awesome perfectly fits every AW custom pistol i have, and it is very great quality

"Works perfect and the sai blu and Tokyo Mauri G18 only thing that kind of sucked is the o-ring didn't last very long for the output valve
