I did something dumb but hopefully nothing permanent and was looking for advice.

I have a Troy 102 (.308). With the factory carbine tube/spring/buffer it was not picking up the next round from the mag, but would eject the old brass no problem. I changed to an A2 style stock but not because of that issue but purely for aesthetics. I installed the rifle length tube, spring and buffer but still had the same problem.

I thought, hmm maybe I'll use the carbine buffer since it weighs less, and fired 4 rounds in succession which all worked normally with no problems picking up or feeding the next round and called it a day. Afterwards I was informed this is a no-no due to the BCG travelling too far rearward and possibly causing damage. I was not aware of this but clearly it makes sense and I now know better.

In the mean time, I no longer have the carbine length buffer spring or the rifle length buffer.

So at the moment I have the A2 stock with a rifle spring inside as per normal, but a carbine buffer.

My question is can I purchase/make a spacer to fit inside the back of the spring to take up the missing length of the short carbine buffer and have something for the buffer to recoil against? The carbine buffer seems to work fine weight wise for the action cycling, I just need to keep it from moving too far back inside the buffer tube during recoil.
 
yes brownells sells a derilin spacer. I made my own out of a piece of 1 inch aluminum cut to the right length, which I cant rember for sure now but think it was 2-5/8
 
Yes the length of the spacer is 2-5/8" and IIRC you have to look under Rock River Arms on Brownells site to find it.

I have changed a couple rifles with carbine tubes over to a rifle length tube and never bought a rifle length spring and buffer. I just installed the spacer and reused the carbine length spring and buffer that I already have.

I did this both because I'm cheap and because it works.
 
Why not just take a weight out of the rifle buffer?
