So, while simultaneously wanting to get engravings on my GR25, I was also curious about threading the outer barrel. As you can see from this picture..
The barrel on the GR25 sniper version (as opposed to the SPR version) is unthreaded. Now, I need to measure the barrel to make sure it actually could be threaded to say 14mm, but what would be needed to do this? Obviously I could not do this myself, but who would be able to do this? Any advice would be helpful.
PS, the only reason I want to thread it rather than replacing the barrel is that AFAIK there are no aftermarket barrels for this AEG. The chamber block is different than that of a standard M4/M16 variant. Thanks in advance.
