Fitting an M4 stock to a fixed buffer tube M16

[RostokMcSpoons]

So as asked in the Quick Questions thread, I'd like the optionn of adding a collapsible M4 stock to my Classic Army AR15-A3 which has a fixed stock tube that looks like this...

Ideally I'd like to be able to fit the old stock back on again, as it does suit the aesthetic of the full length M16... Especially now I've painted the gun

But I do like the collapsible stocks and I'll have a spare shortly

should be interchangeable with classic army collapsing stocks

You'll need an aeg buffer tube with mounting hardware, then you'll likely have to cut down the mounting tube to match the length required in the buffer tube or make a spacer.

You'll also need an aeg sling plate to seal the back of the receiver and guide the wiring into the tube.

Ak2m4.co.uk is a good place to start for buffer tube, they had some with hardware included.

You will also need to rewire as the plugs are going to be in the way. 

But as said above most makes of stock tube will fit , if you want to use a lipo tube, you just need to cut the back of your receiver to match.

I definitely want to be able to fit the existing stock back on - if that's not going to be possible afterwards, I won't bother

Could always fit new wiring so it fits the stock tube and then run an extension from that point so you can swap stocks

Will need some destructive working to achieve that and to be honest by the time you’ve got all the bits’n’bobs you’ll need to achieve the objective you will have spent near the price of a reasonable quality budget gun SO why not just buy another gun ? ?

Oh come on, I have absolutely no interest whatsoever in some sort of budget gun...

None.  None at all, I tell you!

To be honest, I think you're absolutely right.  The AR15 isn't feeding reliably again (even though I've done nothing to it but paint it, and I was very careful with masking all the moving parts), so it's probably not worth spending any appreciable amount of cash on.  I should probably sell it on as a boneyard / project.  The motor and gearbox do seem to be running nicely, it'll be a shame if I can't sort out the feeding issue once and for all.

Me personally I wouldn’t sell it on , you’ll never get even remotely what its worth back as a ’spares or repairs’ id keep it and try and fix it my self .

PS that is a saucy little number you’ve highlighted ! ?
