I went to the range on Saturday. As I planned, the Tubb flat wire spring got replaced with a standard milspec buffer spring.
I also brought more a wider range of ammo, Wolf Gold, Federal Am. Eagle, PMC, Tula plus the same hand loads. I also brought my A2 rifle lower.
Zero mangled brass, with either lower however but failure to feed every other round. The bolt locked to the rear consistently with every empty magazine.
The range was mobbed like Iíve never seen before and Iíve been going there since 2007. Between the crowd and my frustration, I came to the conclusion that I wasnít going to solve this problem right there and then.
My son came with me and he wanted my help sighting in his rifle, so I packed up mine to direct his sight adjustments through the spotting scope. I totally forgot that I brought an extra BCG, and I didnít realize it until we were making our 2 hour drive home.
My plan, give this upper one more try with my spare BCG.
When you say failure to feed, do you mean a malfunction or it failed to strip a round from the magazine?
I would take a hard look at your gas block/tube.
Where is your brass landing?
Did it feed the first round manually and then fail to pick up the next round?
Wow 2 hour drive to the range? That sucks.
