buffer wieght questions

[Brian46]

If you buy a good gas block, like the SLR, it adjusts in 15 positions from zero to .125 opening. At the lowest setting, it won’t allow enough gas for anything to happen.

people said the same about Odin works and I had the same issue.

Recoil impulse and balance are still going to be a problem with a lightweight buffer if the slr is able to close more than the brands I have tried.

You could say the problem lies with the port size barrel manufacturers are using, but then again you need the larger port for the heavier buffer which is why they are doing it in the first place.

I can only equate it to a cars suspension, you want smooth operation like a new mercedes or do you want it to jar your kidneys like your neighbors kids Subaru with cut springs spilling his vape juice on every pothole?

Matt K’s comments are spot on.

I run JP Enterprises silent capture spring systems in most of my rifles, regular weight with the lightest spring. Close the gas block, load one round in magazine, load rifle, shoot rifle, it shouldn’t even eject the brass. Open a click or two, load one round in mag, load rifle, fire. Repeat process until you get bolt lock back on empty magazine. I usually add on e click more to account for a dirty rifle or lower outdoor temps.

If your adjustable gas block can’t completely stop your rifle from cycling there is something wrong with it. Beware some gas blocks like the Superlative arms have two different modes of operation depending on the number of clicks from a reference position, so you could be in bleed off mode instead of wide open. I have only ever used SLR & Superlative adjustable gas blocks. I prefer the SLR’s. I often shoot with the gas block closed, so I don’t have to chase brass in the winter. On my modern Hunter I find it runs well with a LW titanium BCG well at 5 clicks open from closed, but with a full mass BCG I need to run it at 7 clicks.
