Hello all,
I was wondering if the hammer that is included in a CMMG lower parts kit will function with the HK416 upper? I have heard that some hammers are notched and will not make the necessary contacts with the upper. I read that the 2 stage trigger is known to work. A lot of users out there have HK416 uppers that they would like to use with non-HK lowers. Will the CMMG lower parts kit work with the hk416?

Thanks

If the hammer is like the one pictured here:

Then it should be fine.
