Gents,

Building a something out of spare parts I have laying around and have my head turned around as far as buffer/spring combinations go...

For a mid-length gas system, what buffer and spring combination do I want in there if I'm putting on a rifle-length buffer tube?

Thanks.

In most all cases, the rifle length receiver extension uses only rifle length spring and buffer.

Running a carbine length parts combo allows the gas key to impact the lower receiver.

This is my new build, in progress.
Mid length gas with an A2 stock and rifle buffer.
I like Springco's chrome silicone springs.

Standard rifle buffer and rifle spring in a rifle buffer tube UNLESS you have the special spacer that takes up the internal space so a carbine buffer and spring can be used.

It'd be cheaper to put a stack of quarters in there instead of that buffer.
