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.

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.

Note the Canadian C7A2 with 20" A4 upper and collapsible stock.

The C7 has been used by various Canadian, British, Norwegian, Dutch, and Danish forces over the years.

C7A2

With Canadian involvement in Afghanistan, Diemaco and the Canadian Forces have developed improvements to the C7A1 to better suit the operational situations at hand. The result, the C7A2, has a four-point telescoping stock unit similar to that of the C8 carbine and a 3-rail TRI-AD I mount on the front sight triangle.

The selector lever, magazine release, and charging handle latch are ambidextrous. Also, the C7A2 is issued with green colour furniture as standard. These weapons are often seen with a similar plethora of accessories as their American counterparts given the overall commonalities of the system and the rail mounts.

The C7A2 is also issued with the C79A2 ELCAN optical gunsight with 3.4× magnification but with a uniform green rubber armored coating, but some soldiers who are issued it have either been issued or have purchased sights like the EOTech holographic weapons sight and the Trijicon ACOG.

Within an eight man section, six soldiers will normally carry a C7A2, the section commander and second in command, two grenadiers and two riflemen, with only the machine gunners carrying a C9A2 LMG. The C7A2 is considered a "mid-life" upgrade for the C7 family. The addition of the TRI-AD rail mount has made it easier for soldiers to attach accessories such as laser designators and tac lights.
