Ok,
So, in short, I've got a barrel on my Armalite upper (with M4 feed ramps in the upper) that has standard AR-15 (non-M4) ramps.
I'm planning on replacing my forearm with a Larue 13.5.
While I've got everything apart, I'm thinking I just want to put an M4 barrel extension on.
So I called Stag Arms to see if they sell an M4 barrel extension for their 20 inch barrel (the one I've got on the rifle)... and they tell me that it must be installed by a gun smith.
I was unable to determine if this was because machining WILL be involved, or if they were more covering their butts.
I'm assuming that their own barrels will have extensions that are very similar between batches, and the removing the current one and replacing it should be a piece of cake.
...and that so long as I use a set of Go / No-Go gauges to verify things are proper, there shouldn't be any issues.
Given that the barrel is chrome lined, I don't see how there is anything that a gun smith is going to be able to do.
Am I full of crap?
