arhandguard

The most common AR-15 handguard materials are aluminum (primarily 6061-T6, with 7075-T6 in premium options), carbon fiber for ultra-light builds, and polymer for budget or drop-in setups. Aluminum dominates free-float M-LOK designs because it balances strength, heat dissipation, rigidity, and cost. These same principles apply directly when choosing an AR-10 M-LOK handguard, where greater size, weight, and recoil demand careful material selection for balance and durability. Handguards protect...

How to Compare Free-Float and Drop-In AR15 Handguards Quick AnswerFree-float AR15 Handguards mount only to the barrel nut and never touch the barrel, delivering better accuracy consistency (especially under bipod or sling pressure), superior heat management, and full-length modularity with M-LOK or Picatinny. Drop-in AR15 Handguards clamp between the delta ring and front cap or sight base, making them cheaper, lighter in many cases, and far easier to install, but they can transfer pressure to...

To check AR15 Pistol Buffer Tube compatibility, first measure the outer diameter (approximately 1.148 inches for mil-spec or 1.168 inches for commercial) to match braces or end plates, confirm the tube threads cleanly into a standard AR-15 lower receiver, verify that the buffer and spring match your gas system length and barrel (often H2 or H3 for short pistols), and ensure overall length and configuration keep the firearm a legal pistol. Pairing a correctly matched AR15 Pistol Buffer Tube...
