SPEED-TAC AR Bolt Carrier
Never Drop A Magazine Again!
In order for a fully-loaded AR-15 magazine to be inserted into the gun, an excessive amount of force is needed, which doesn’t always result in the magazine latching properly.

ST3 – NP3® Coated
The ST3 uses industry leader Coating Technologies to coat the carrier.
NP3® – (Electroless Nickel / PTFE) and NP3+ (Electroless Nickel / PTFE with a High Phosphorus Electroless Nickel undercoat) are durable, self-lubricating Nickel / PTFE composite coatings that can support a wide range of engineering applications.
With a 0.1 coefficient of friction and up to 500 hours salt spray resistance this thin, hard and lubricious coating combines a low coefficient of friction with wear resistance, electrical conductivity and increased protection from corrosion.
The coatings autocatalytic (electroless) deposit reduces the thickness variations that are associated with electrolytic deposits and creates a thin uniform coating that is accurately deposited across complex geometries. – Coating Technologies
ST2 – Nitride Coated
The ST2 is coated by H&M Blacknitride™
Nitride is a class of chemical compound in which nitrogen is combined with an element of similar or lower electronegativity, such as boron, silicon, and most metals.
A black coating that makes the gun’s metal 10 times stronger than it was originally. Nitride coating sickens the surface to make the carrier extremely lubricated.
By nature of the process, the steel is hardened through a thermochemical treatment to the steel which makes the steel harder and resistant to water penetrations. H&M Blacknitride+™ extends barrel life, makes cleaning easier and protects the part from corrosion. – H&M Blacknitride+™
