If you have first hand experiance with them please provide the following details.

Brl length: 14.5", 14.7", 16"
Gas sytem: Carbine or Middy
Buffer weight: Carbine, H, H2, H3 or 9mm

You may want to ask the Larue guys. I believe they include them with their Stealth uppers.

I think this may be one of them too,

I went ahead and ordered a Springco "blue" spring from brownells 943-000-018. For $19.12 it comes with a 5 coil XP CS extractor spring as well.

I measured 4 new M4 actions springs which had the following measurements when new.

Lewis Machine and Tool (LMT) SS 10 1/2"

Brownells SS 078-000-105 10 3/4"

Colt Defense LLC SS 17-7 160-307-104 10 7/8"

Springco/Tactical "Blue" CS 943-000-018 11 1/16"

I've been using the Brownells springs and have not been impressed with the life of the springs. I'll try the Springco "Blue" Spring soon for function in a 14.5" M4 with H2 buffer.

ETA LMT spring measurement.

Sprinco springs are one, important, part of the equation of Mike Pannone's extreme reliability package. Their Machine Gunner's Lube kicks ass, too.

I am running the Sprinco Red buffer spring with the extra power extractor spring (p/n 25006) , with a Colt H buffer, in a DTI 16 LW carbine with Std "F" marked front sight. Using Federal XM193 no problem so far.
