Magpul UBR stock on aeg

[Eenthuncob]

I know this might be a long shot but here it goes.

 

I’ve recently bought a replica UBR stock and with it not coming with the aeg adaptor and really struggling to find the adaptor online.

 

Has anyone got a good idea of how to attach the the UBR buffer tube to my Krytac even though it’s a gbb buffer tube if I remember correct.

 

Thanks.

Got some pics? My UBR reps all came with a buffer tube and screwed straight into standard thread on an AEG/GBB

Yeah I’ve read online that they are meant to come with the adaptor. Just my luck it didn’t come with it.

 

Ive got some pictures anyway.

Nope, looks exactly like mine, what won’t it fit? That threaded buffer tube screws straight into airsoft receivers?

 

[Eenthuncob]

No it won’t screw into my Krytac.

 

Already had a go it fits on ok just no way to secure it, I think I’ll have to get incentive to get it to fit.

 

There used to be aeg adapters but can’t for the life of me find one.

 

Might have to weld some metal with a hole in there for a screw to go through.

Why doesn’t it fit then, if It screws in? What model Krytac?

 

Mine just screwed perfectly into my Vector stock adapters, do you need a lock nut?

 

Is the fit on your Krytac military or commercial fit?

If you decide you want to sell it, give me a shout please

[Eenthuncob]

There is only a fixing point and then you use a screw with a metal plate to fix it in place.

[Guest]

Ahhh, not threaded then, bugger.

 

I just put a folding stock adapter on my daughters Patriot to do exactly what you want.

 

One part of the adapter screws to the receiver, over exactly (but shorter) mount you have, then the buffer tube screws into the rear

Hmm that could be an option.

 

as you can see from the picture the insides are both different, my wife’s uncle makes ride on steam trains so is rather handy with welding and metal work so he might be able to weld me something inside the UBR buffer tube to get the screw and retention plate in.

out of interest where did you buy it from where they didn't give you both aeg and gbb stock tubes?  I have a UBR hardly used, don't use it anymore so will get rid if interested

Good idea, just make sure you get a block welded in that stops the buffer tube rotating as well, tightening the single screw won’t do it

I got it from dhgate.com, came from China so probs won’t send it back, I probs should of asked in the wanted section.

 

i didn’t know that GBB and AEG buffer tubes were different when ordering the stock.

 

If you don’t use the stock anymore I’ll happily take the aeg buffer tube off your hands

Mine also, but the fitments I’ve used haven’t been an issue

Yeah I've seen ones going for around 60 bucks and no mention of AEG tube.  Dang hard to get hold of now

[ak2m4]

Sounds like a potential plan lol

[Eenthuncob]

Could be I will see what my wife’s uncle can do and if it’s not possible will do what is said above.

[Eenthuncob]

Sorted the UBR stock guys. Got an old bugger tube and removed the runners for the crane stick drilled some holes to screw in place and hey presto it fits nice a snug, will need some new batteries though as my 1300 lipo is a very tight squeeze.

Hi, can you help me with this as well please. Also got one from dhgate and have the same issue you had. How did you fix it please?

What I did was get a normal buffer tube that will fit the gun (or the one you’ve already got) and remove the notices and metal from the bottom of it where the stock would attach and click into its different positions. Then get any sharp edges off by sanding.

 

After the buffer tube is smooth attach it to your gun and put the UBR stock in place making sure it’s straight and then use the screw holes in the bottom on the UBR stock to tighten it in place. 

 

Im at work at the moment so can’t get any pictures for you but I’ll put some up if needed.

 

hope this helps.

[Spider1982]

Thank you bud.

 

i did actually manage to get one with the correct AEG tube - though it required modification.

 

It does also mean I have a spare AEG adaptor too now as got one that wasn’t needed lol.
