I just shot my sabre 16” with Giselle rail and gas block. Seems a little over gassed and ejection was sometime inconsistent. At times it was right at 3oclock but the randomly would chuck one at 1. Is that maybe due to it being shot only once. Does anyone also know what weight buffer the sabre come stock with and would a heavier buffer or spring help?
Look on the buffer…should be marked c, h1, h2, etc. If not, weigh it. And yes, a heavier buffer could help. What ammo were you shooting?
PMC x tac 55g, aac 55g, pmc 62g green tip.
I did notice less gas’s with some of the ammo. But some of the ejection was pretty inconsistent. Seemed like when I sped up shooting the bras was going at 2 o’clock. Will a buffer help with gas in the face?
No. The buffer slows things down. You can get a different charging handle or do the RTV hack on your own CH (google it).
My PSA AR-15 was over gassed and throwing brass about the same. I put an H2 Armaspec SRS buffer system in it. It helped a little but not enough to matter to me. I’m thinking about an adjustable gas block. Also wondering about how much the “brass pattern” actually matters. There isn’t any failures to feed , stove pipes or other jams or failures to lock back on the last round. So should there be any worry over where the brass ends up if there isn’t any other real problems?
I will look into that. I’m thinking about the superlative adjustable gas block. Do you know if I will fun I to issues changing it since the Geislee one is pinned in place?
Yeah there was no issues with reliability but I would like to eventually suppress it and being that it’s already over gassed idk how that would work.
You can take the Geissele off. Iirc it is pinned and has set screws.
Took it out today and ejections wasn’t erratic. The 55g was ejecting right at 3 and no gas. The 62g x tac was ejecting closer to 2 but not nearly as bad as yesterday.
this to me is what i think. As long as the rifle is firing and cycling without issue no matter what ammo i feed it, i really could care less what the brass pattern of ejection is.

I believe that it does mean something if you are trying to tweak it in to absolute perfection. My personal philosophy is that it’s better to be a little over gassed than under gassed.

ok, but to what end… you say tweaking it into absolute perfection, and i say what is that absolute perfection. and why does it matter regarding where the rounds eject the empty shells from?
If a rifle is badly over gassed and the BCG is slamming back it will do damage. The idea of fine tuning a rifle would be to get a rifle firing so it does the least amount of damage to itself while firing dependably. Right? The way a rifles ejects can show if it is somewhat over gassed and can give a shooter an idea of somewhere to look if there are other issues.

im on board with tuning it to keep it from damaging itself. i dont know anyone who wouldnt be. That said, if the rifle is firing and ejecting between 1 and 6 oclock, without damaging itself in any way we… obviously no one wants to purposefully damage their rifle by shooting it,… Hell I dont wanna damage any of my firearms at all.
