Description
Bootleg built this one from 7075 billet aluminum and gave it a MIL-SPEC hard coat anodized finish, so it can take a beating without flinching. At 7.2 ounces it trims noticeable weight off your build, and a big part of that comes from deleting the forward assist. Fewer parts, fewer snag points, and a cleaner-looking receiver that still runs the way you expect an AR-15 upper to run.
What Sets This Bootleg Billet Upper Apart
The forward-assist delete is the headline, but the details are what builders tend to appreciate. It carries a low-profile brass deflector and a captured dust cover door pin, which means no more chasing that little E-clip across your bench during assembly. That small touch makes install and future maintenance a lot less aggravating. Billet machining also tends to hold tighter tolerances, so you get a consistent fit when you mate it up to your barrel and handguard.
Building With the Bootleg AR-15 Upper
This is a bare receiver, so plan on adding your own barrel, bolt carrier group, charging handle, gas system, and handguard to finish the build. It works with standard AR-15 lower receivers and the usual parts kits, so it drops into most builds without drama. If you're chasing a lighter carbine or a fast-handling setup for competition or dynamic drills, cutting weight up top is one of the more effective ways to do it.
Who This Upper Fits
Home builders and folks upgrading an existing rifle will get the most out of it. You'll want a Picatinny top rail setup for mounting optics, and it plays nice with the accessories most AR shooters already own. For anyone who never used the forward assist anyway, losing it is an easy trade for the weight savings and the tidier look.

Frequently Asked Questions
Does the Bootleg Billet AR-15 upper come with a forward assist?
No, the forward assist is deleted by design. Bootleg dropped it to shave weight and reduce snag points, which is how the receiver gets down to 7.2 ounces. If you rarely or never use a forward assist, you won't miss it.
Is this a stripped upper or does it come assembled?
It's a bare receiver, so you'll be adding your own barrel, bolt carrier group, charging handle, gas system, and handguard. It does include the low-profile brass deflector and a captured dust cover door pin, so those small assembly headaches are handled for you.
Will the Bootleg upper fit standard AR-15 parts and lowers?
Yes, it's built to work with standard AR-15 lower receivers and common parts kits. Billet machining tends to hold tight tolerances for a solid barrel and handguard fit. As with any build, double-check fitment with proprietary or oversized handguard systems before you commit.
What is the dust cover pin design about?
The low-profile brass deflector captures the dust cover door pin, which eliminates the need for the usual E-clip. That means less fumbling during install and simpler maintenance down the road. It's a small detail that anyone who has lost an E-clip mid-build will appreciate.
