But it's pretty, rugged, nice overkill. Atleast if the buffer tube breaks, that's cheap to replace. But if I'm running a cheap pot-metla reciever, and it breaks, and cracks the gearbox? Looking at a new gun then, right?

There are ways and means though, are there not? Such as chemically bonding the buffer into place, and if / when it breaks, using a different chemical to break down the binding agent. But the reciever just *feels* flimsy on this gun. And I'd like those markings and such.

Well the barrel has a pleasing thickness to it, and the buffer-tube is going to be aftermarket because the gun came with a cheap solid stock. Do you really think the external upgrades are *that* bad of an idea?

It's more just the fact that the reciever is currently made of cheap crappy pot-metal, and I would very much like to upgrade to an aircraft-grade aluminium body, much like the real deal. A lot more rugged, durable, and with the armory markings, nicer to look at. I've seen the videos on youtube before, none of them show the external deconstruction though. The thing that is not tackled is how to remove the HUGE top rail, or the method by which it's attached. 'Nor is it mentioned how to get that MASSIVE foregrip off.

Hello all! This is my first post here on the forums. I'm here to look for some help or make an enquiry at the very least. I recently got my grubby little paws on an A&K Mk 12 Mod 0 SPR. I love everything about the gun with one exception - I feel that a full aluminium reciever would bring everything together neatly, improve the durability of the gun, and would just be a 10/10 upgrade... The problem is I've never disassembled an M4, let alone one with a set of modifications like the *MASSIVE* rail that runs over the TOP of the reciever all the way to the front ironsight. So what I'd like to know is... *IS IT POSSIBLE* to take the entire external barrel assembly off of this gun, lift out *ALL* the internals, and drop it into an ENTIRELY NEW *black* M4 Body? And if so, how? Sorry to ask such a complex yet noobish question, I really really really hope someone can help. This thing could really become a dream-gun if I can just make some "Small" mods to it like this. Thanks in advance!
