Spikes Tactical is firmly established in the AR-15 market. This company is well known to produce some of the highest quality uppers in the business. The ST-15 LE line of upper receivers was originally designed as fully mil-spec compliant upper for LE customers. However, that same level of reliability and attention to detail are now available on the civilian market.
The upper receive uses a mil-spec 16” barrel. This is the short barrel possible without having to worry about NFA laws. The barrel has a 1:7” twist rate. This twist rate is optimized for heavier/longer .223/5.56mm projectiles in the 60-77 grain range, although it will still perform well with 55-grain ammunition. The barrel is ported with the reliable carbine length gas system. The carbine length gas system has ben utilized by the United States Military for several decades and has proven itself to be a reliable system.
The end of the barrel is topped off with an A2 style flash hider. This muzzle device is very effective at mitigating flash signature. However, it also functions as a compensator. The top portion of the muzzle device is ported, allowing the gases to escape only out of the top of the muzzle device. This has the effect of pushing down the muzzle, thereby preventing muzzle rise.
This upper comes with the Spikes Tactical BAR2 Picatinny hand guard installed. This rail system allows you to install your Picatinny compatible accessories.
This upper is a great multi-purpose upper at a fantastic price. Don’t miss out on this deal!
