#Improvement

Paul Leitner-Wise of Leitner-Wise LLC has published a teaser for an upcoming new improved AR-15 bolt carrier called Long Advance Bolt Carrier. At first glance, it may look completely identical to any standard bolt carrier, however, that’s because the changes are incorporated into the cam track geometry which is probably not something you can spot right away unless you compare it to a standard bolt carrier.

After being cancelled in mid-2016, could the M4 Carbine upgrade program still be alive? That is the suggestion from a line in the US Army’s justification for its research budget in the 2018 National Defense Authorization Act, which references an “M4A2 Plus Rifle” as a new weapons development effort:

According to a Military.com article, an element of 1st Battalion, 6th Marines will be deploying a 13-man squad of Infantry fully equipped with M27 IARs, suppressors, drum magazines, and other pieces of experimental gear. Called the “Über Squad”, it will be chosen from companies within 1/6, and will use the gear through an entire workup, training, and deployment cycle to Europe. From Military.com:

For those of you that were lucky enough to miss the first iteration of the Urban Carry making its rounds on social media, the guy below does a pretty good job of highlighting how fast you can get a gun unholstered with the unusual design. Urban Carry seems to have addressed this with their G2 model according to a press release.

The US Army’s plan to wrap new technologies and commercial off the shelf (COTS) improvements into the M4A1 rifle has apparently been canned. The program, called M4A1+, was originally intended to upgrade the M4A1 fleet with new COTS rails, back up sights, flash hiders, triggers, and other improvements, but it seems the service will push forward with the basic 22-year-old M4A1 design for now.
