I know this gets asked a lot, but have yet to see anyone using a Magpul UBR stock. I have a 18" barrel, AA, and a mid-length gas system. I also use a BCM m-16 carrier.
When using factory ammo, Hornady or AA, 115 or 123. Occasionally the charging handle pops back. I do believe it is bottoming out hard, enough to unseat the charging handle. I have a carbine spring and buffer, would a heavier weight help? Or possibly a pig tail in the gas line?
Thanks
