Very disappointed with the service. Still waiting for item. Have not received answer from
Company.
All goods as Received described and within lead times quoted
Initially order for a M4 we open, it's not compatible. When I mount it, it's impossible to mount the upper.
I bought this for my Goldne Eagle GBBR gel blaster and it fits perfectly!
Not just for mk18mod0, if you want to build any old school rifles in late 1990s to early 2000s, this is a really good choice.
