The AMT is not a big rifle, although it visually appears to be larger than it really is. The charging handle is on the right side of the receiver and is extremely easy to grasp. The large ejection port is also on the right side and there is no ejector door as on the M16. The hollow black plastic pistol grip is quite comfortable to use and has a removable end cap to allow storing the cleaning kit. Disassembled into its several major components, the SIG AMT strips to this level in less than 30 seconds.
Every part is machined and finished to a truly high level of the firearms art.
Notice the length of the recoil spring assembly. It has a very pronounced effect on reducing the .308 Win recoil. From a side view the AMT appears to be a square and perhaps bulky rifle which could be uncomfortable to use. This is definitely not the case as it very readily falls into your shoulder when firing. The relationship between buttstock, forward hand rest and trigger assembly are excellent.
