For those that still like the classic 20″ barrel with a rifle-length gas tube, carry-handle and rifle-length recoil system. I have a similar A4 that I built with the PSA A4 upper and it shoots fine for CMP Service Rifle matches.
PSA AR15A4 Review
And in my area the 20" barrel is desireable for the extra velocity/performance vs. shorter barrels.
On other 20" builds I put a collapsible stock on with a carbine buffer, like what the Canadians have done, and everything runs fine. The best of both worlds.
