Brownells Rifle Uppers for Sale

Brownells, Inc. of the United States moved into in-house rifle uppers by 2018 with its Retro AR-15-pattern complete uppers, followed in 2019 by the BRN-180 and later the HK416-compatible BRN-4 assemblies, establishing rifle uppers as a continuing house-brand focus. Distinctively, Brownells concentrates on two niches within rifle uppers: detail-correct Retro clones for period-accurate builds, and modern short-stroke piston uppers that drop on standard AR-15 lowers, with the BRN-180 running without a buffer tube for folding-stock and suppressor-friendly use and the BRN-4 delivering HK416-style performance and parts compatibility.
