[ARCHIVED THREAD] - Too much buffer?

Posted: 12/17/2011 6:06:03 AM EDT

I have a DD middy that I'm running a Spike's ST-2 buffer in. The action seems to cycle really slowly, slow enough that you can actually feel the bolt go back into battery after the shot.

Its on an LMT lower w/ sopmod stock. I traded out the factory buffer for the Spike's. It worked fine in the 14.5" middy it was in before. I'm not sure if I need to go with a lighter weight buffer or just need a new spring.

Any ideas?

What kind of ammo are you shooting?

The whole point of the middy system is a soft shooter. You add that 4.3oz buffer, almost H2 weight, it well slow it down even more. If your shooting light .223 that even less gas.

Spikes sells its middy upper with the St-T2 buffer. Works fine for me with all ammo except Tula., which I never shoot.

Federal M193 and PMC M855.

It worked well in the 14.5 middy I had before.

Thorough cleaning and lube, and try again?
Try a standard buffer? New Spring?
Gas block properly aligned?
Try different bolt carrier? (Gas key leaking)

The buffers job is to control cyclic rate. In a semi auto AR15 it's not that important, but in a M16 it's more critical. The heavier the buffer the slower it runs....

Run a standard weight buffer for normal functioning.

have an RRA buffer in mine which is the heaviest you can get ... I think 5.6 oz see link below
slows everything down, feels smoother and less kick
the only problem I have is when using some crappy steel cased russian ammo which is under powered
