Fast Cap Adapter - Co2 Cylinder Cartridge Quick Change - Compatible with BYRNA SD, EP, LE, HD (Black)

I bought the Fast Cap Adapter for my Byrna SDXL launcher and I am very happy with it. It makes changing the CO2 cartridge so much easier and faster than using the factory cap and the magazine tool. I can just twist the cap by hand and replace the cartridge in seconds. No more fumbling with the tool or worrying about losing it.The Fast Cap Adapter is also compatible with the Byrna Boost Adaptor (XL), which allows me to use 12 gram CO2 cartridges instead of 8 gram ones. This gives me more shots per cartridge and more convenience, as 12 gram CO2 cartridges are widely available everywhere.The Fast Cap Adapter is made of stainless steel and has a polished finish. It looks great and feels sturdy. It fits snugly on the CO2 chamber and does not leak or rattle. It is easy to install and remove, and does not damage the launcher or the cartridge.I highly recommend the Fast Cap Adapter to anyone who owns a Byrna SD, EP or HD launcher. It is a great accessory that improves the performance and usability of the launcher. It is worth every penny and I am very satisfied with it.

Fits. Works. Improves. What more do you want?Even if you tighten it a bit more with the mag tool and have to loosen it with the mag tool (which you don’t have to do at all, but you can if you want), it’s still a massive upgrade from the original design.

Great fit. Makes switching air cartridges fast and easy without any tools!

Well, I was trying to post a photo of how it fits me Byrna LE model, but Amazon policies don't like that.So, does it fit? Yep. Easy to screw on/off using your fingers? Yep. No need to use that wrench part on the mag. Not sure why Byrna didn't make a thumb screw cap, but at least somebody did.

Allows tool-less replacement of CO2 cartridge, well made, nice option for the Byrna pistol.

Fits perfectly in both my Byrna SD and LE. My only issue is the white lettering. That was easily resolved with a black inkzall.

Much faster to reload

I love the idea of having the ability to change a co2 cartridge on a Byrna without a allen wrench (even though there is a built in allen wrench on Byrna magazines).II bought 2 of these and same results on both on 2 different Byrna SDs. The cap will screw in without binding - without a co2 cartridge. But with a co2 cartridge the cap binds within one thread screwed in. I did not force it because I didn't want to cross thread these caps or my brand new BYRNA SD. And trying several different brands of co2 cartridges - the same results on all. Maybe these caps were designed for the larger Byrna that holds a 12 gram co2 cartridge, but this product is advertised as fitting the SD. And a message for this supplier: I am planning on buying several more Byrna's to give away as gifts. So far I have bought 3, 2 are gifts to family. I would have bought one of these caps for each of the gifted Byrna's.
