"Got these for my SAI 2011 5.1 AW mags and love them. Size difference it very noticeable compared to stock and makes a great seal. One of my mags had a sealing issue requiring me to push up on the mag from the bottom to seal the mag to the nozzle. Quick swap to these and no more issues. Easy and simple upgrade I now use on all my mags. 5/5

"You can see the difference of the size of the rubber. The seal is much better than the original one on a WE Tech Hi-Capa magazine.
by Ethan H. on 08/02/2018
"Almost a requirement.

GET THIS, and put it in your AW custom or WE Tech double stacked 1911 mags.
The difference it makes:
These lips protrude further up and out of the top of your mag, and will get a great seal on your loading nozzle/BBU, increases compression greatly. Less gas loss due to a greater seal.

Put a tad bit of silicone oil on the lip.


You may notice that the first round to load into the chamber makes your nozzle stick and you may have to manually push the nozzle back to activate the spring. The protruding lips on the mag is pushing into the nozzle. Either deal with that or upgrade the nozzle spring to a very strong level, like 150. After the initial round is engaged the Blowback action will make sure to feed your mag the rest of the time.
