Recoil Spring Question

Post by NorincoKid » Wed Oct 31, 2018 9:10 am

Hey guys. I'll admit to not being super knowledgeable about the AR stuff. But I got a few parts in trade, and figure I had a stripped lower in the safe maybe I'll put together.

In the lot of parts I got, a incomplete LPK, some monstrous quad rail thing, and a buffer & spring.

It's been awhile since I've had an AR on hand, but this looks very, very long compared to what I remember having on mine.

The Spring itself measures out to 17" , looks like 42 coils. I thought I remembered the recoil on my carbine being 10-12" or so? The buffer itself is is just under 5" long, maybe 4 7/8" ish?

Are these .308 parts? They seem to be considerably different than any standard parts I've had before. Any input is appreciated, thanks.

from a foggy memory, hope this helps

regular AR-15
buffer spring approx 12.75 inch, number of coils doesn't matter and will vary from mauf to manuf
a rifle buffer tube ( or receiver extension ) measures about 10 inches
a rifle length buffer measuers about 6 in

carbine length 11.25
buffer tube = 7
buffer = 3.25

for 308

all I have here is a carbine spring and it measures about 11 in

Thanks.

Yeah then I'm not sure what this is from. Its 17" long, maybe its just a stretched out and/or hammered spring?

Not outside the realm of possibility, but it came with a buffer on/in it. Also was some odd "rings"? and a firing pin, which looks like it may be a little longer than standard AR too?

FYI...An AR buffer will not fit inside a shotgun mag spring

Is it a flat wire spring were the coils/spring flat instead of round? If so it may likely be a Tubb's shooting system spring which are considerably longer than a standard spring.

At 17" long I can't think of any spring, other than a shotgun tube spring, that it could be.
