Tubb 42 coil spring in 5.56 guns and why it runs almost everything

[georgeib]

I am not an engineer, but I am an inveterate tinkerer.

All things being the same, my experience with (16-inch carbines and 20-inch) USAMU "National Match" M16s and AR-10s, heavy (XH and H3) buffers and Tubb springs give me less perceived recoil, less movement off-target (faster recovery for rapid-fire strings), and abuses my brass a whole lot less with moderate and top-end pressure precision loads.

Which Tubb springs are you using, the 36 or 42 coil?

In A5 tubes for the 5.56, the 5.56 spring.

In A5 tubes for the 7.62, the AR-10/SR-25 spring.

Try the 42 coil in A5 5.56 guns. I’m curious how it runs for you.

Got one ordered, per the info in your thread, sir. Eager to see myself! Thanks for that info.

The 42 coil runs excellent for me, supp/unsupp with a properly ported barrel.

Likewise, hence this thread to compare to others. Thanks for adding your experience.
