RRA lower with RRA LPK and RRA 2 stage NM trigger.

Talon Arms SPR Upper with 18" WOA SS barrel.  Remington and Hornady 55 grain ammo. 1st time out to shoot the rifle.

I had several FTF and FTE problems (say 7 out of 45).  Couple times it looked like the round just stovepiped in ejection port, keeping the returning bolt from feeding the next round and returning to battery.

Currently using a Spikes Tactical ST-T2 buffer.  Should I go to the basic carbine buffer and give that a shot before I assume it's something else? Seems like someone told me that the ST-T2 might be too heavy a buffer for a middy system.

Thanks guys.

Yeah. I would try a lighter buffer first.

Thanks...

I'll change it out and see what happens.
