Thank you for sharing your hands on experience!!Hello everyone I thought I would post my views on the AR-15A4 and M4. First a little background on me. I am a gulf war veteran with two tours in the gulf war I’m also a retired deputy sheriff so I know the M16 and AR platform extremely well. The M4 comes in two ways for civilian use either a 16” barrel or a 14.5 inch barrel the majority of civilians seem to be buying the M4 more then the A4. Personally I believe the civilian buy this because that is what the majority of police and military use. So why do the police and military use the M4 mainly because it is a CBQ weapon which is fine but you lose muzzle velocity and energy 300 to 400 FPS. Keep in mind the 5.56 was designed for a 20” barrel I was issued a M16 20” in the gulf war. now for the A4. Although I have a colt M4 I prefer my Colt A4. I have cleared many houses with my M4 when I was a deputy I can assure you I can do the same with a A4 the 20” barrel dose not hinder my mobility even in tight quarters. My advice to anyone thinking about getting a AR-15 is to get a A4 first then a M4. I personally disagree with the military ever adopting the m4. Yes I have one because I used one as a deputy. The A4 gives you longer range much higher velocity softer recoil. Again I am speaking from real world use both in combat and urban. This is just my opinion hope this helps
I was hoping the 6.8 x 43 Special Purpose Cartridge would be adopted for the standard military round with a 15 inch rifle barrel. It was pretty effective I read to about 400 yards.My preferred length is 11.5-12.5 suppressed. A 12.5" 6.8 Special Purpose Cartridge is what I really wished we had. Love it.
