Not sure which one you've seen,but they look better than the extended ruger charging handles. They look just like the real deal, & there's way more to grab on to. They also hide the ejection port,so you don't see where the airsoft Chassis has been cut. That's my opinion anyway. I did another...
M249 build
I finally finished my M249-22 build. Added a real saw pistol grip to go along with the real bipod and buttstock. Waiting on the heat shield. I got the charging handle to work with the ruger charging handle. I put a video on YouTube,it should be under m249-22
In process of building mine.
Looks great. I'm in the process of building one also. So far I've installed a real m249 bipod,& buttstock. I have a gsg 110 rd drum. Still have to get the ruger 10/22. Hopefully next month. I've got an idea on how to make the charging handle work from the m249...
