How to Build an AR-15 Lower & Upper Receiver Set
Welcome to the Combat Hunting AR15 parts and accessories for sale. Looking for how to build an AR-15? The first step is to upgrade your AR-15 lower receiver and AR-15 upper receivers with our AR-15 parts and accessories, available at wholesale prices. We offer a wide selection of aftermarket AR-15 lower parts kits for Colt carbines and accessories and DPMS LR-308 parts to upgrade or build your rifle. Our AR-15 furniture kits include rugged AR-15 stocks, featuring classic AR-15/M4 6-position collapsible stocks and grips combo kits and Mil-Spec AR-15 buttstock models, recoil-reducing, and complete stock and grip combo sets. For builders customizing their bolt carrier group (BCG) or weapon’s finish, our Flat Dark Earth (FDE) AR-15 furniture kits and parts provide a sleek, tactical appearance. Complement your AR-15 stripped lower with the best AR-15 pistol grip or an ergonomic grip to reduce hand slippage and minimize wrist fatigue during combat or hunting operations.
Choosing the Right M-LOK Handguard or Tactical Quad Rail
We suggest optimizing your AR-15 handguard setup with our premium M-LOK handguard designed for AR-15/M4 carbines and rifles and the M&P 15 Sport I-II-III. Our M-LOK handguard selection is vast and designed as a direct two-piece drop-in handguard upgrade. We offer a full inventory of carbine-length, mid-length, and rifle-length M-LOK handguards; AR-15 quad rail models; KeyMod handguards; and heavy-duty free float handguard aluminum systems that fit directly into standard delta ring assemblies. These tactical rails provide an expansive platform for mounting lights, lasers, and vertical foregrips without requiring permanent gunsmith modifications to your carbine rifle.
Upgrading Extended Bolt Releases & Ambidextrous Controls
Enhance your AR platform's build performance with the mil-spec AR-15 buffer tube and H2/H3 buffer for recoil management. Our inventory includes the best and most popular AR-15 muzzle brake models and clamp-on upgrades, such as the ambidextrous bolt release levers in many colors similar to the Magpul BAD lever, the monolithic single-piece alternative to the BAD lever, or rugged clamp-on battery assist devices. These tactical options feature fully ambidextrous bolt release configurations and clamp-on battery assist devices designed to accelerate magazine reloads and clear firearm malfunctions directly with your trigger finger or opposite hand. The AR-15 Extended Bolt Catch Release Lever really completes your lower receiver parts setup. We also suggest the AR-15 ambidextrous safety selector switch or a comprehensive AR-15 lower parts kit (LPK).
