Just before SHOT Show, Knight’s Armament announced that they will be bringing out old school products and making them available for the commercial market. They are calling it The Vault. The items in the Vault are not just products that they used to make, but these are products that were not commercially available for civilians. They were originally made for government and defense contracts. And there were some small numbers that leaked out to civilians in the past but now you can own them at normal prices.

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:

Spuhr is bringing in their HK collapsing stock. It has been used by Swedish Home Guard.

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. ArmyTimes reports:

I came across REV Arms at a local gun show. They claim to have the lightest 15″ aluminum rail on the market.

In the past couple of months, Salient Arms International sold matched uppers and lowers. They were on sale for $350. I bought a set and in the past two weeks, built my version of the Salient Tier 1 AR-15. For those not familiar with the Tier 1, here is a review.

Mission First Tactical is making a 7″ aluminum quad-rail for the AR-15.  Called the T-MARC (Tekko Metal AR Carbine) Integrated Rail System, it replaces the standard handguard with a unit that has four Picatinny rails.
