Complete 7.5 Takedown Upper 5.56/.223 MLOK Handguard

Question

Q: I am currently building a lower receiver to accept this upper. I was wondering if you could recommend a buffer and spring that would work for this. preferably one that could also handle being suppressed.

Accepted Answer

We use a 4.3oz buffer with a mil-spec spring in the 5.56 uppers. We don't recommend suppressing a 7.5 inch 5.56. You would be better off with the .300 AAC if you want to do it on such a short barrel.
