Going from rifle length gas to mid-length gas.

[buzziebells]

Hello.  I have been building 300 blackout SBR's and now would like to move up to .308ar's.  I have a Remington R 25 in 7mm-08.  I would like to replace the factory barrel with a 12.5" .308 barrel.  The 7mm-08 barrel is rifle length gas.  The 12.5" .308 barrel is mid-length gas.  I am retaining the factory A2 stock and buffer tube.  I have been researching this, and if I understand correctly, I should be good to go by retaining the factory stock, buffer tube, spring and buffer, correct?  This gun will be run suppressed 100% of the time.  I will be installing a SLR Rifleworks adjustable gas block to help control the over gassing.  Any more suggestions?

 

Thanks.

Yes. An extra heavy buffer from heavybuffers.com. I use one in my AR-10 SBR that I built last year. She runs pretty good, even without an adjustable block. Even suppressed.
