As to the removable carry handle with rear sight...this is a TRUE carry handle and NOT what some other companies put on their guns and CALL carry handles.
As to the sights...the front sight on the Professional Rifle has Trijicon inserts. While better visibility is always good, I have a preference for the XS Sights AR sight sets. Of course, that would mean changing both the front and rear sights.
Something else that the gun comes with is a 100-yard test target. Of course, and no offense meant to any manufacturer, how well the gun shoots in the factory and how well it shoots in YOUR hands is always different. Most of us aren't as good as the guns are. So, that's why we take it out to the range. With full magazines and an ammo can full of cartridges, off I went. On the day I took this rifle out, the weather was cool (about 60 degrees F), overcast, and sometimes raining gently. Bench-rested at 100 yards, I had no problem consistently putting out sub-MOA 3-shot groups. Off the bench, firing unsupported, I couldn't keep the groups quite as tight, but again--that was me, not the gun.
I went through twelve 20-round magazines and ten 30-round magazines. I kept the bolt lubed with MiliTec, but other than that didn't give any cleaning or maintenance to the weapon during the firing. I didn't experience any malfunctions, misfeeds, or failures of any kind. Along about five 20-round magazines into it, I realized that my firing hand was more comfortable than normal with AR-style weapons and I have to credit this to the ergonomically shaped grip. I found that I wasn't squeezing it quite as tight as I normally would--because it felt more secure in my hand due to shape and texture.
When I was finished shooting I had to field strip it again (I did it once before shooting) and was reminded again of how tight these guns are built. Pushing out the pins isn't as easy as it is with some other manufacturers' guns. Tolerances aren't as loose. To me, this and all of the upgraded design features, not to mention the case and accessories, easily justifies the higher retail on this gun when compared to other "standard" AR style weapons.
I like this and I like the Massad Ayoob Signature Elite Rifle even more. Look for that review in the future!
