Some may want to swap out the flash hider for other accessories. Like the HK model, the Colt M4 Ops features that same awesome shooting Carl Walther match grade barrel liner. For most ammo, you will never have to tune the spring, but it is a great feature to be able to tune the reliability for hot or cooler velocity rounds for optimal reliability. The Umarex line does not require that you run “hot” high velocity ammo for good reliability. This maximizes reliability with faster or slower. 22LR AR-15 conversions, you can tune down the spring tension to even run subsonic rounds reliability.

The other two goals were to maximize accuracy and reliability, which they did with a proprietary bolt design and spring which can be adjusted and tuned for more or less spring tension via a hex wrench. To do this, Umarex developed semi-sealed upper and lower receiver internals for less maintenance. Part of the unique internal design was to reduce jams and decrease cleaning after firing those very dirty little. On the outside, the trigger feels like a really nice AR trigger, but it’s drastically different internally than any standard AR. The internals are also unique to Umarex, differing significantly from the standard Ceiner style AR conversions.

One of the things I really liked about the HK, which carries through on the Colt M4 Ops rimfire AR-15, is that there’s enough heft to make it feel real vs the uncharacteristically light S&W M&P1522. 22LR Colt M4 Ops is lighter than a typical 7-7.5lb 5.56 version. My assumption is that it would be tough to hit this price point with a 7075 Type III anodized receiver set when a lesser expensive aluminum and finish would work perfectly in this situation.Īt 5.9lbs, the. The finish on all the aluminum bits is of high grade anodizing, but Umarex does not specify what Type (I, II, or III) anodizing (also, the upper and lower are an unspecified type of aluminum). The HK’s front sight was plastic, but the front sight on the Colt is metal. The front and rear take-down pins on the HK were aluminum the Colt’s are steel. Unlike the S&W, pretty much everything on the Colt M4 that can be made of metal is, with the exception of the rear sights. 22 ARs and I can say the Umarex Colt is very solid, well built gun with excellent fit throughout. 22LR rifles, then it will come as little surprise that the internals, AR style magazines, barrels, and accuracy has been duplicated in both the HK and Colt models.Īt this point, I own all the major brands of.
