I am interested in the input/experiances of anyone who has used the Sprinco/Tactical springs action/buffer springs
If you have first hand experiance with them please provide the following details.
Spring type :White/Blue/Red
Brl length: 14.5", 14.7", 16"
Gas sytem: Carbine or Middy
Buffer weight: Carbine, H, H2, H3 or 9mm
Your results: Did the spring improve reliability or decrease reliability. Did it reduce recoil or increase recoil.
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 Springs.com "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.
Let me know what you think.
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.
