Inner Barrel Length

[Lockdown_Neil]

Hi Guys

I've just bought a 7'5" outer barrel for my SRC M4, my question is what length inner barrel do I need?

Any help would be appreciated 

Thanks

How long is your old outer barrel? Subtract the length of your new one from that, take the difference off the length of your original inner barrel and bob's your uncle.

Why the hell didn't I think of that!
