Drilled a hole through the side of the tube, put a rod in there with a hole in it's side and secured it to the receiver through that. |
Yeah? My clone UBR (from out-of-country, didn't know Huang was selling them) came with two buffer tubes:
one is full-length (190mm) & threaded for GBBR receivers, the stock mounts with one M6 countersunk screw through the endcap into the end of the buffer tube, similar to real-steel
and one "stubby" (68mm) with M5X85mm screw for AEG receivers, the stock mounts with two small grub screws through the underside of the stock tube that bite into matching divots on the underside of the buffer tube. (Kinda weak setup imho.)
With the AEG buffer tube in place, I've still got 28.5mm X 105mm of empty stock tube; plus there's a slot running the length of the tube's bottom I can stuff the wiring into. It occurs to me that simply backing off the two grub screws would give access to any batteries stored behind the buffer tube (dur), so modifying the stock tube end cap to flip open would really be a waste of time. :banghead:
Heh, still not sure I even want this on my SR25K... not a Magpul fan normally, but this stock sure is comfy. Heavier than my full stock too, should help offset some of the front-heaviness of a PEQ & bipod.
Whoops, off-topic(-ish). scurvythepirate's linked battery would fit easily, but 800mAh is a bit low for my liking. They've got a
1000mAh version, but it's 125mm long; I'd have to mill out a lot of material & weaken the stock tube considerably to fit it. I like the A123 cells, but could only fit one in the stock tube... maybe two more in the stock compartment. Hmm.
