i know the info is on the forum, but search isn't working for me right now (invalid security token)
what are the lengths for a CAR buffer spring and for a rifle buffer spring?
aprox how many coils in each?
thanks in advance!
Looks like...
rifle- 12.750"(relaxed) with 44 coils.
carbine- 11.250"(relaxed) with 39 coils.
Can they reliably be interchanged?
Zip
PS: The spring from my old SP1 has 37 coils.
The acceptable lengths for the springs are as follows. Relaxed and coil count means nothing.
Rifle 11 3/4- 13 1/2 inches.
Carbine- 10 1/16- 11.25 inches.

gotm4-The different is in the length of a rifle buffer and a CAR buffer. The springs are also different. You can use a CAR length buffer & spring in a rifle length stock if you buy a spacer to make up for the additional length of the rifle length receiver extension. You can't use a rifle length buffer & spring in a CAR length stock (CAR receiver extension is too short).
A lil' something I put together for these questions.......

Now you need one with all the various weight buffers! That would take a while!
That's a great visual representation!

I believe that there is already chart here with a breakdown of the buffers and their composition.
