This is the text of the original post:@FP1201 Maybe we are both trying to say the same thing and not understanding each other. And I’m not trying to sound like an jerk or anything, just so nothing can get misconstrued…as simple as you can make the next statement, what point is it exactly that your attempting to make?
Does anyone know why Springfield has discontinued the AR pistol platform?
I called the Armory and was told it was due to a supply issue. Does this seem
like a lame excuse to anyone but me? Thanks.
I replied: Might be onto something: the only things "different" on an AR Pistol is a rounded buffer tube, shorter barrel and short gas tube (possibly handguards) nothing really difficult or significant.....(irrelevant text)
Now this discussion started around a Gun formerly in production by a reputable company, and according to OP per his call to SA it's a supply issue, but we don't know what items are in short supply, my assertion was there are only a few things different on what the industry calls a "Pistol" that being the obviously shorter parts that differ somewhat from those associated with Carbines, Rifles, SBR's and even "Other" firearms.
What it evolved to seems to be the suggestion that no such parts exist or aren't unique to those guns with the charismatics of a Handgun, to which I say there are Industry standard references. Sure you can put what ever sized barrel you wish on an upper receiver, makes no difference UNTIL you pin it on a lower *, then you have a whole other set of Laws to comply with.
* There is a term called Constructive Intent, where if you had both the assembled upper and lower but were separated, it could be construed that you intended to mate the two together. (simplistic explanation)
