Dueling 12.5's - build planning, ersatz-GL/SSC vs GAU-5 ASDW

[JediGuy]

Honestly, Stick, with options at 10.3/11.5/12.5 with good ammo, for practical purposes, do you see much point in anything longer than a 12.5” besides maybe an 18” SPR?

Sorry that I missed this question. I think once we start to reply with yes or no, we get back to condensing that idea that we may as well all use 12.5s. It also brings up the question of ammo and by that point we are on the slippery slope to all arguing that "Stick sucks, we should just carry Mk18s".

"Stick sucks, we should just carry Mk18s".

That would be interesting, since I believe you shared pictures of your go-to 10.3” carbine. I guess haters gonna hate.

Game On! It's not "pure" in light of the G3 being toast, but I'm using a Combat Rail Lightweight and planning MBUS 3 sights calling it "ASDW-PIP" for "Product Improvement Program." I'm gonna have the anti-rotate tabs chopped, since I figure the Air Force gunsmithing shop wouldn't particularly care about commercial warranties. Dvor got the QRB for $370, so that was like a sign from above that it was Go Time.



Left to do: the folding grip, lower receiver (I need to call my FFL and see if they still have Aero faux-M4's), barrel/gas block and BCG (all in the Rosco Sauce Pack).
