Every build starts with a good upper, and this one is forged from 7075-T6 aluminum. Forging packs the grain structure tighter than billet, which is why it's still the go-to for hard-use guns. It's machined to M16/M4 military standards, so your barrel, handguard, and bolt carrier all drop in where they should. M4 feed ramps help rounds run up smoothly from the magazine. The top rail is MIL-STD-1913 Picatinny, ready for your optic or backup sights. Ships stripped, so you can build it out however you like.
