Need some help/advice from you AR Pros out there on INGO...
I have a new AAC brand 16" barrel, in the 300 AAC Blackout caliber, with the factory low profile (Non-adjustable) gas block that came with it.
The gas port location on the barrel supports a pistol length gas tube.
This:https://www.midwayusa.com/product/1...roduct-shipped-today-product-description-link will be the muzzle break.
I will be using a new PSA Nickle Boron bolt carrier group (if that makes any difference??).
My primary loads will be 110gr. Nosler and V-Max rounds, loaded up to the higher end of specs from these Co. data lists. I will probably move up to a 125gr. Ballistic tip later.
At this time I do not ponder on any suppressed loading.
I would like to use this upper build on one of my A2 (Full length) stock lowers.
My question is: Do I use the Rifle buffer and spring for this upper, or should I start with a Carbine length buffer and spring??
I have both to try, and I just ask for thoughts for the best cycle of the bolt carrier group??
I kind of just now got the .223/5.56 rounds/uppers where I want them, and am going to see what the Blackout does for me??
Thanks in advance..Bill.
