NBS 16″ Slick Side Billet 9mm SOCOM M-LOK Rifle Kit

NBS 16″ Slick Side Billet 9mm SOCOM 1:10 M-LOK Upper Assembly

An affordable pistol upper assembly without cutting corners. This means using quality American Made handguards, paired with a 16″ Nitride treated barrel chambered in 9mm.

This also means taking the time to ensure that the upper will function reliably. We use Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the properly torqued barrel nut and muzzle device.

Bottom line is this: you hear all the time about guys buying a budget upper and it not lasting or having to send it back because of some hardware defect or other issue caused by a careless assembly process. That is why we use quality components and assemble each unit to the highest standard of quality. We want your upper to function flawlessly out of the box. In fact, we guarantee it will.

Dirty Bird PCC (9mm / .45) Receiver Extension / Buffer Kit.

The Dirty Bird PCC (9mm / .45) Receiver Extension / Buffer Kit cuts no corners. It features a true Mil-Spec 6-Position Receiver Extension (buffer tube) machined from American Made 7075-T6 Aluminum, 8oz 9mm / .45 Extended Solid Recoil Buffer – no sliding weights, a chrome silicon buffer spring, hardened castle nut with staking cuts and mil-spec end plate.

When it comes to your buffer system, quality counts. If the spring rate isn’t correct, it can cause cycling issues. Poor quality aluminum can lead to a fracture in the receiver extension. Unfortunately, there are a ton of receiver extension / buffer kits on the market (import AND domestic) that suffer from one or all of these shortcuts in the manufacturing process.

You have Dirty Bird’s word that this kit is made from the finest materials, using modern manufacturing processes. If you’re looking for true mil-spec quality, don’t pay more, don’t settle for less; this is your kit.

Includes:

• 7075-T6 Aluminum 6-Position Mil-Spec Receiver Extension (7075-T6 Aluminum is nearly twice as strong as 6061)
• 8oz 9mm / .45 Extended Solid Recoil Buffer – no sliding weights
• Hardened Castle Nut w/ Staking Cuts
• Mil-Spec End Plate

Made in the USA
