Thread: A class Thumbhole stocks , what do you prefer

Where'd you buy it from? Probably worth telling them

New Zealand's favorite :p , GC Auckland

...its a Bushmaster.

The lug is not functional, but best to nip a bit more off, as you'll get different opinions form different AOs.
Mine was the same. Passed by Hamilton, bit sussed according to Auckland.

Hacksaw and file, problem resolved.

Thanks Ant, and Gimp, glad you spotted it now...
Once decapitated, whats the best thing for finishing the steel to prevent rust...

[Sorry to hijack this thread, willbe back on topic shortly ]

I just cold blued mine.

Received my Windham SRC last week, it has been fitted with one of these: AR-15 Tac Carbon Systems A Cat Stock | Trade Me

I fucking hate it. Grip slopes too much, making it hard to hit mag release and safety, and it's a little too chunky for my liking, stock may suit something you shoot off a bench better.

The rifle was originally fitted with a commercial-spec buffer tube, trying to figure out what's on there now underneath this things so I can buy something else. Will probably end up importing a mil-spec carbine buffer tube, not keen on an ATI anything which is all that seems to be around here.

Actually are all tube internal diameters the same? If buffers etc are all the same I could just buy the tube itself.

Buffers are all the same (diameter - carbine and rifle buffers are different lengths/weights and don't interchange without changing tubes and springs). that stock is the biggest piece of shit there is. Except maybe the $650 carbon fibre one that doesn't even come with a buttplate

It will be an A2 tube, which is longer than a carbine tube. You dont want to use your rifle length buffer in a carbine length tube, which is what i think you are implying you want to do. If you think about it hard enough you will figure out why...

Good to know about the buffers for future shenanigans. The fit and the build of the stock seem ok don't get me wrong, but it comes across like the person that designed it never bothered to pick up and use the rifle once they'd fitted this stock.

So you're saying that this stock will have an A2 tube+buffer+spring+whatever else goes in there under it, instead of the carbine setup it had when it left the factory? Which comes across to me as a less than ideal situation.

see my edit re: buffers above


rifle/carbine systems will function equally reliably - rifle systems have a softer spring though and spread the impulse of the reciprocating mass of the bcg and buffer over longer time so are "softer" shooting. but don't work with a carbine stock obviously.

Yeah I'm just deciding whether or not I should be upset that it's been changed by the importer to something other than a factory equivalent. I mean I can get a rifle length mil-spec stock if that's what matches the installed it's not a big deal, it's whether this new tube will adversely affect performance. I'm also looking at a suppressor in the near future, is a rifle length tube gonna matter much? 16 inch barrel, carbine gas system.

I have to agree with AzumitH, this looks errrr....

An old motorsport saying is "Its not how good you race, but its how good you look racing..."

To me our pride & joys (thats our guns, not our kids), should be both functional and look good, but no doubt for many its also a tool, so functional is all it needs to be.




Oh, i just had a good look at my 'lug' and do apologize to GC but they did actually chop most of the bits off the lug and cold-blued it.
So now its just a blob below the gas block...

nah a rifle or carbine length buffer system will be equally reliable. There's no option for a carbine buffer system with a thumbhole stock.

It would be difficult to manufacture a thumbhole stock for a carbine buffer tube. Magpul did a pretty good job with their fixed length MOE carbine stock but it is a multi piece design that includes unique metal parts to make the fastening work in the absence of an A2 style stock screw. I'm guessing that the shortest thumbhole design on the market is the servo version.
