I think I'm going to contact QC10, but wanted some opinions here as well.
Original Config
Hardware
QC10 9mm Glock lower
Lone Wolf Glock Cut bolt
3.5" barrel
AAC ECO-9 suppressor
H2 Buffer and quarters
Carbine Spring
This config, shooting 147 gr freedom reloads and 135 gr critical defense - functioned great with glock mags, except on one of the last mags of critical defense, broke the bolt catch.
Emailed QC10 for a new bolt catch spring, and they told me I should be running somewhere around an 8 oz buffer. So I bought an 8 oz 9mm buffer from KAK and ran that, but now I am getting FTE issues using my latest batch of Freedom Munitions ammo (ran some older FM ammo fine on a previous range trip). Thinking maybe this batch of ammo has a little less umph, but that is purely speculative. I want my rifle to run everything, even weaker loads. Still locks bolt back though.
My ejector does wiggle, but I think it is supposed to.
What should I try?:
try a wolf extra power spring with KAK 8oz buffer (if my thought process is right, this would be the opposite way to go, but I do have one)
chop a little off of my current carbine spring
run the H2 Buffer again with the wolf spring and more quarters (would probably work somewhere in middle of original H2/carbine and 8.0oz buffer/carbine. Also have a seekins bolt catch that is supposedly stronger than normal bolt catches)
or ??
Would rather have a rifle that beats itself up a little and functions 100% over one that has less recoil but may not eject rounds properly.
I am also going to check out where the ejector sits tonight - I have read about people bending theirs inwards until it is almost touching the bolt, I don't know where mine is currently sitting.
And is there a different subforum that I should be posting in or is this the right one for this question?
Edit: So I have bent my ejector to make better contact with the brass, per QC10s recommendation. However, I noticed now that my bolt has a very thin wall appears to be eroding. Could this cause my FTEs or problems down the road?
