  1. Bench rest shooters have found NO accuracy advantage over the 5.56. There is no operational or functional advantage. The 223 Wylde is merely a marketing ploy to sell more guns. Just buy firearms chambered for 5.56 NATO. Now in other nations where military calibre weapons are not allowed for civilian ownership, this switcheroo benefits them or if you are in the export business.

  2. @bearcreekarsenal I just bought your 556 10.5 complete rifle for my gf's first AR but only because the 223 wyld was not available. When will those uppers be back in stock so I can upgrade her .

  3. More powder in a 5.56!? I stopped watching this guy right there. There is NOT more powder in a 5.56 vs .223. There is NOT a pressure difference in 5.56 vs .223.
    I'm not going to give this guy the data that he should have researched himself before attempting this video.

  4. The 5.56 is my wife. The 223 is my girlfriend. The 223 wylde is that sexy hooker who can be a little of both, but can't fully be neither. in desperate time, there is no need to be picky.

  5. Finally shot mine yesterday. Shot 5.56 and .223. A few jams with the first couple of mags but once the oil got down everywhere it needs to be, no issues at all. Put about 200 rounds through it and it got better and better. This is my first AR so I really have nothing to compare it to, but I am very very happy with it.

  6. Nice Vid, but to clear a few things up the main difference between .223 and 5.56 is the free bore or the jump to the rifling. The .223 has .025" freebore length, where the 5.56 has .050" freebore length. The rest of the dimensions on the case are negligible. The difference in pressures ( the .223 max pressure being 55,000 where the 5.56 being 62,000 ) is due to where the civilian market tests for case pressures vs. where the military tests for case pressure. The civilian market tests towards the back of the round where as the military test at the top of the round. If both were tested in the same spot the pressures would be close.

  7. Great topic and video! IMHO the 5.56 NATO chamber is designed for the military with extra tolerance in the free bore diameter to allow for longer duty intervals between cleanings by allowing more tolerance for carbon and debris buildup before you start to have extraction issues. Whereas, the 223 WYLDE chamber, with tighter free bore diameter (by a hair), is designed for match users that are able to clean the carbon buildup from the barrel on shorter intervals between matches.

  8. It seems that every weapon in your introduction is throwing the spent cases forward towards the operator's two o'clock position. This type of ejection is indicative of an over gassed gun that is putting extreme pressure on the bolt carrier group.
