External Rail Upgrade

[_Shatteredamethyst]

I currently have a TM M4 CQB-R and I'm looking to upgrade the external rail but unsure what its compatible.

Any help would be great!

Keep it a CQB-R

(fuck M-Lok, Keymod or any other fancy attachment system, good old picatinny is where it's at for cool points)

Ignore the boring farts, is it NGRS or standard?

In any case a new outer barrel is required because of the delta/gas block assembly being in the way

Assuming it's the same as every other Marui with a front sight block I've ever had, you can just knock the pins out and remove the front sight block. Once that's off it's a simple case of unscrewing the barrel nut. Shouldn't be any need for a new outer barrel unless I'm wildly mistaken, unless the OP is simply more comfortable not having to do any of the aforementioned.

Edit: I'm aware saying 'just' and 'simple case' is very easy to say when you've done it multiple times. But there are a decent portion of resources to guide through the removal of a front sight block out there.
