Israel is changing to Tavor assault rifles. The Pentagon is still evaluating a replacement to the M-16/M-4 family, and it is possible that the Tavor may be a candidate depending on how it performs with the IDF.
I have no problem with the AR-15/M-16 family of rifles. I carried one in the USMC infantry during Desert Storm, Somalia, and as a contractor in Iraq back in 2004/2005. Was it the best caliber? No. The rifle itself was functional and reliable with a bit of care taken to maintain it. With that said, I would like to see a move to a newer platform for front line troops such as the FN SCAR, in the 6.5 Grendel, or 6.8 SPC calibers (I prefer the 6.5 Grendel).
With a barrel and bolt change, and follower changes for the magazines, the M-16/M-4’s currently in service can be upgraded for the new cartridge and supplied to rear echelon troops until the SCAR can be fielded. All of the M-16/M-4 rifles can then be broken down into parts (removing the full auto & 3 round burst parts and receivers)and sold to law abiding civilians through the CMP program.
With that said, I am going to take my AR out for some exercise later today after I vote.
