NEW SPR TROUBLE ON FIRST RANGE TRIP.

[georgeib]

THANK YOU.
After posting this- I saw the excellent thread here on springs. I liked the reviews of the 42 coil Tubb spring, and was considerng it already when I saw your fast response. Should I try the 36 or 42?

My take away from lysander's posts in that thread is that buffer weight has MUCH more influence than spring weight. I would experiment with Tubb's Carrier Weight System, if I were you.

I think the 42-coil is for AR-10s/SR-25s. Maybe the short ones are for 300 Blackout? I don't remember specifically, but don't over-spring.

I used the Tubb weight for years in my National Match (yes, to shoot at Camp Perry) M16s. The two-piece set-up wasn't so much a pain in the backside as it was annoying to have the tungsten insert, then the steel sleeve fall out when stripping the rifle for cleaning. I solved that by using an XH buffer.

Yes sir- I knew the 42 coil was to be for .308, but several here & elsewhere report using them in 5.56 guns to great effect.
Wondering while at Camp Perry- did you see any using the NM bcg? Thoughts on that?
I am def gonna order a Tubb Spring. When I do & can get to the range to test, can I safely assune that if it will workk with M193, its good to go with the heavier stuff? Dont want to have to use my Match ammo for testing too much if possible.
