Will this be the correct spring for and AR-10 in .308 or 6.5 Creedmoor?

Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on April 01, 2022

The Strike Industries AR Carbine Flat Wire Spring could be used in an AR10 if it uses a carbine length buffer tube. However, the Strike Industries AR-10 Flat Wire Spring would be a better option for an AR10 and it can be found at the link below.

Is the carbine flat wire spring ok with mid length gas system? It seems like there's not enough resistance when charging so worried about bolt bounce

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on February 14, 2022

Yes, the Strike Industries AR Carbine Flat Wire Spring will work as long as you have a standard carbine length buffer tube. How effective it will depends on the specifics of your set up. Please email us at techsales@opticsplanet.com for more information.

Bryan Reis, member, from CA, United States, asked on January 08, 2022

I have a 450 bushmaster 18” with mid length gas tube and was recommended to use a carbine spring even though it’s a mid length gas tube. Is this ok

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on March 07, 2022

Yes. The Strike Industries AR Carbine Flat Wire Spring is essentially an upgraded stock carbine spring. It will provide increased service life of the platform, smooth's out the shooting cycle, and greatly outlasts the stock spring. Increased bolt load, in addition to decreased compressing force increases reliability in cycling.
