Big Bore AR-15: Tuning the 458 SOCOM (pt 2) - “It’s Alive!”

***My apologies for the poor audio quality in the video. (My feelings are not hurt if you had to click away!)***

“It’s Alive!!!”
I’ve finally gotten the 458 Upper to run reliably by using a Lancer L5 Mag, Enhanced power Sprinco Blue carbine spring, H1 Buffer, and modifying the profile of the exterior edges of the feed ramp. Hallelujah! The beast is alive and accuracy is superb at 50 yards.
