Well I did fix one of my problems now to fix the other problems. I will post an update next week. Who knows what I will break next.

i built up a 10.5" sbr using a rra upper. im having issues with it short stroking. i use commercial .223 ammo and the lower has a tapco mil spec m4 6 pos stock, spring and buffer. i have 2 different carbine springs (one is about an inch longer) and two carbine buffers (stock and a spikes t2). so far all combinations have the same issue. what set up do i need to go to in order to make this thing rock?do i need to run 5.56 nato ammo instead since it has higher chamber pressures than commercial .223? any help would be great thanks

Is it ejecting the empty case?

Does it pick up the new round?

it does not eject the spent case and it tries to feed a new round causing it to jam

Since u have already tried different buffer I would look at the extractor........maybe try one of those o-ring upgrades

I hade the same problem with mine. I used a Wolfe extra power spring to fix the extractor in my rilfe.

but would the barrel length have that much affect on the the extractor? i used the same bcg in my 16" and 20" guns and it functioned flawlessly.

It has more to do with dwell time.

My only real issue was with steal case ammo.........

The extractor actually broke the rim of the casings off and became lodged in the chamber....beast to get out.......

Mine would leave the spent case in the chamber. You could lock the bolt back the brass would fall out.
