Does it matter which spring you use for a 10.5in SBR/Pistol?

[Chris42393]

Good evening everyone! I bought a regular carbine lower awhile back... Do you think a regular carbine spring will work for a 10.5in rifle? Or is there a special spring needed to run SBRs? If so, what do you recommend?

Thanks everyone!

Regular spring should be fine, its the buffer you should be changing if anything. H2 or H buffer for a 10.5" will likely be better overall than a carbine buffer. If you want additional tuning you can always get an extra power spring.

My experience is that H & H2 buffers are always better than CAR buffers.

Use a quality action spring. Cheapies will quickly sack.

Agreed on the Colt Carbine Spring, and an H2 buffer (at least). Most 10.5 barrels are over gassed... In fact, I can't think of any that aren't. An H2 is probably fine if there's no suppressor.

Yep, that's the one. Good price and free shipping. Hard to beat that. I'd do 2 of them.

I used to get them at Brownells, but I haven't ordered any in a few years.

I have several SBRs. I will only use Colt, Vltor or Sprinco springs.
