On my iPhone helping a friend troubleshoot. Spring looks short compared to ones I've used.

My search and PDF capabilities are limited

Carbine buffer spring length should be around 11" right?
Will buffer springs take a set and compress over time?

His spring is 10 3/8" out of an LMT lower which seems a little short
Another used spring I have from a VLTOR kit is 11"
Two brand new BCM springs measure 12"

RIFLE: 11 3/4 inches (29.85 cm) minimum to 13 1/2 inches (34.29 cm) maximum.

CARBINE: 10 1/16 inches (25.56 cm) minimum to 11 1/4 inches (28.58 cm) maximum.

Hmmm so the LMT is a little short

I wonder what negative effect a 12" spring has in a carbine. Now I have two issues. A too short LMT spring and 2 too long BCM springs

Thanks for the assistance

ETA. So the LMT falls within spec

Thanks. I have the PDF on my iPhone but I can't search it. And I got frustrated scrolling through 300+ pages
