Product DescriptionTune your AR-15/M16 recoil system with the LBE Unlimited H1 Heavy Carbine Buffer, designed to help slow bolt carrier group (BCG) velocity for improved cycling and reliability. This carbine-length H1 buffer contains a blended internal weight setup (one tungsten and two steel weights) to achieve the H1 recoil profile, making it a great option when balancing barrel length, gas system configuration, gas port size, and ammunition type. Built for use with a carbine buffer tube only, it features an aluminum buffer body and is made in the USA.Product HighlightsH1 heavy carbine recoil buffer designed to help slow BCG speed and support reliable cyclingInternal weights include 1 tungsten weight and 2 steel weights for H1 buffer tuningCarbine-length buffer intended for use with a carbine buffer tube onlyDurable aluminum buffer body constructionMade in the USASpecsBrand: LBE UnlimitedManufacturer Part Number: ARBUFF-H1UPC: 784682014349Platform Compatibility: AR-15 / M16Buffer Type: H1 Heavy Carbine BufferBuffer Length: CarbineBody Material: AluminumInternal Weights: 1 Tungsten, 2 SteelWeight: 3.8 ozCountry of Manufacture: USADisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
