S.E.Pedersen Posted October 16, 2012 Report Share Posted October 16, 2012 I haven't seen this done before.. so I thought I'd share it with you.. I found out that the airsoft buffertube for the m4 collapsible stock, had about the same outer diameter as the Milspec buffertube for the real AR15s.. I'll lett the pics do the talking.. (airsoft buffertube for the M4..) Link to post Share on other sites
PureSilver Posted October 18, 2012 Report Share Posted October 18, 2012 What receiver is that? Some of them - WA-pattern GBBRs, for example - are already threaded to accept RS stock extensions, which means you don't have to get the hacksaw out. Link to post Share on other sites
U-TAG Posted October 18, 2012 Report Share Posted October 18, 2012 Ptw's and GBBrs can accept RS stocks, Ptw's need a channel for the fet board to be machined in. Link to post Share on other sites
crackisbad Posted October 19, 2012 Report Share Posted October 19, 2012 look at the third and fourth pictures guys, see the channels on the inside of the tube? This is for a regular AEG Link to post Share on other sites
PureSilver Posted October 19, 2012 Report Share Posted October 19, 2012 Well, what's the OD of a regular AEG stock extension? Link to post Share on other sites
NeoVeNoM Posted October 22, 2012 Report Share Posted October 22, 2012 Using an AEG stock tube, putting it in a real steel full stock so you can install it on a TM style AEG M4 receiver. I say that's pretty well done. Nice job. Link to post Share on other sites
SpankyTheDolphin Posted October 22, 2012 Report Share Posted October 22, 2012 Most airsoft guns use a mil-spec buffer tube, while real civilian rifles come with a commercial style buffer tube. The commercial is a little wider so commercial stocks will fit on a mil-spec buffer tube but will be a little loose. I rarely see people use a real steel stock since they're usually 2x the price of an airsoft copy. Link to post Share on other sites
DFM56 Posted October 30, 2012 Report Share Posted October 30, 2012 Anyone have a source for cheap full stock screws? I kind of want to try this with a MOE rifle stock and a spare receiver extension, but the cheapest screw I can find online is $15 shipped. Link to post Share on other sites
DFM56 Posted November 14, 2012 Report Share Posted November 14, 2012 So, instead of chopping up a spare receiver extension, I had an adapter piece machined. Now I can't wait to get home and see how everything fits together. Damn 10 hour shifts...I'll post the print later, maybe someone can make one in CAD so it can be 3d printed for anyone that can't chop up a spare buffer tube. Not sure what compatibility would be like with anything but VFC receivers, though. Also, the MOE stock doesn't have nearly as much battery space as I thought it would. I still need to measure it, but I probably won't be able to get more than a 1600 mah 11.1 and mosfet in it. Link to post Share on other sites
DFM56 Posted November 17, 2012 Report Share Posted November 17, 2012 Finished product with an MOE rifle stock Quick sketch I made for the part. It could probably be 3d printed for cheap, I just don't have any CAD programs. Colors show what dimension corresponds to what part of the receiver as well as how much needs to be added for a good fit. You don't want the part to be the exact same size as the receiver, otherwise it will be impossible to get on. Dimensions will probably need to be changed for different brand receivers. These dimensions fit my VFC receiver perfectly. I don't even need a screw to hold the stock on, yet it's still possible to remove it. I don't have any pictures of the part out of the stock, and.. well.. it's pretty much permanently in there right now. I did go a bit overboard with this. I didn't have a spare buffer tube that fit well on my receiver, and I'm kind of crazy about things like that. The stock tube has come loose from a 2' fall before, so I wanted something that would hold up to some abuse. Thanks to Pedersen for the idea, I didn't realize how 'easy' something like this could be.
