Item is what it is. Doesn't work with DBoys gas version to convert it to spring.

I bought a double bell Kar98k bolt 'cause my last one broke, and so far it's worked great. One thing I've noticed is how It's tough to prime the rifle when there's no bullets loaded in the rifle, but you can still get it to work. Nice item, good quality 10/10 forget Taiwangun.com lol.
