Questions & Answers 2
-
Does this offer last round bolt hold open w/ aero lower?
Jeremy · Jan 20, 2026AT3 Support Team — No, the AT3™ 9MM 16″ Assembled Upper does not include last round bolt hold open (LRBHO) functionality out of the box.
-
What buffer weight and spring do I need for the AT3-ASAL-9MM-16-BLK upper?
Mel · Apr 26, 2025AT3 Support Team — It is best to start with a standard carbine buffer spring and a buffer weight around 3.8 to 4 ounces. Adjustments can be made based on your specific bolt carrier group weight and shooting conditions, but this is the baseline recommended setup.
