Luth-AR AR-308 Buffer Body Features The Luth-AR AR-308 Buffer Body is built as a factory replacement for AR-10 pattern rifles chambered in .308 / 7.62mm giving owners a direct source for a worn or damaged buffer. Matched specifically to the AR-308 platform rather than the lighter AR-15 buffer it is sized and weighted to work with the heavier bolt carrier groups and recoil springs found in .308 pattern rifles. Proper buffer weight is central to reliable cycling affecting how the action handles recoil impulse and how smoothly the bolt carrier returns to battery. Replacing a mismatched or worn buffer with this Luth-AR unit helps restore consistent function to an AR-10 build. Weighing 5.35 ounces the buffer body is sized to fit within a standard rifle length AR-308 buffer tube without modification. Luth-AR designs its components for straightforward installation letting builders swap the part during routine maintenance or as part of a larger upgrade. The buffer fits Universal AR-308 platforms making it a practical option across a range of AR-10 pattern rifles rather than one specific brand. For builders maintaining or fine tuning an AR-10 rifle the Luth-AR AR-308 Buffer Body is a dependable factory-spec replacement part.
