I am attempting to lighten the ejector & extractor springs in a couple of
AR-15 based target rifles. My wife and I shoot in a league in May, and
it's all standing (offhand), one shot at a time. I would prefer A) not
to bounce hot brass off adjacent competitors, and B) not have to hunt for
brass flung all over the place.


why not put a valve on your gas port?

My FN-49 has an adjustable gas port, and I can park the brass at my
feet, or hurl them into the sun.

I thought about that, and there are aftermarket gas tubes with valves
built in. That would require a fair amount of disassembly to retrofit.
I've also heard that the gas tube valves can get clogged up & are a
royal pian to clean. I figured I'd fuss with the springs first & see how
it works out. It only takes a couple minutes to pull the bolt &
disassemble it completely so it's an easy thing to do.
