The Small Parts You Need To Assemble A Complete Upper
Handy kits gather up all the small parts needed to complete a functional upper receiver. Eliminates the hassle of tracking down every component separately, including hard-to-find pins and springs, so you can start a custom build knowing you won’t be held up waiting for that one part you forgot to order. Select the stripped upper, barrel, gas block, flash hider, bolt/carrier, and handguard you want, then purchase the completion kit to fit the handguard style and gas system length. Each kit contains original factory parts, so you can install parts made by the manufacturer of your receiver. AR components from one manufacturer will fit another manufacturer’s receiver, but fitting may be required. Use Standard (STD) kits with GI-style snap-on handguards. Includes gas tube, delta ring, handguard retainer ring, barrel slip ring spring, forward assist assembly, ejection port cover assembly, flash hider crush washer, peel washer, and all required pins, springs, and clips. Use Free Float (FF) kits with free-float forends that attach to the barrel nut and do not require delta ring handguard attachment system. Includes gas tube, forward assist assembly, ejection port cover assembly, flash hider crush washer, and peel washer, plus pins, springs, and clips.
