Full description and what we offer
Mid State Firearms has been assembling and selling custom AR-15 uppers since 2013 from Clinton, Mississippi. What started as a focused AR platform builder has grown into a full-service parts distributor stocking thousands of components for AR-15, AR-10, and Glock builds.
Mid State specializes in three things:
Every upper that leaves their shop has been test-fired before shipping. If it's listed as in-stock on their website, it ships that day.
They stock:
| Category | Notable Items |
|---|---|
| AR Uppers | 223 Wylde, 300 Blackout, 5.56, 7.62x39, 450 Bushmaster |
| Barrels | Fluted, stainless, nitride, from 7" pistol to 24" rifle lengths |
| Handguards | M-LOK, quad rail, free float options |
| BCGs | Microbest (HPT/MPI), nickel boron, TiN, left-hand options |
| Glock Slides | G17, G19, G22, G23, G26, G43, RMR-compatible, MOS-compatible |
| Finishes | Oilslick (rainbow), TiN, PVD coatings on lower and upper parts |
Mid State runs constant deals on blemished uppers and grab bag uppers – mismatched barrel/handguard/BCG combinations that sell for 40-50% off retail. Customer reviews consistently mention getting pristine-looking uppers with no visible defects, shipped in 3-5 days.
"Just ordered a grab bag upper for a budget build. Wasn't sure what to expect, but took a shot for the price. It was shipped the same day of order, and just received a few days later. The one it came with was just what I was looking for." – Terry S
Their support team (Allen and Zak) answer calls and texts around the clock. But the real differentiator is what happens when something goes wrong.
Multiple reviews mention:
Free shipping on orders over $350. Most orders arrive in 3-7 days. They offer a 5% discount (code: TAKE5) on your first order.
Contact Information: - Allen: 601-201-9665 - Zak: 601-720-8252 - Email: [email protected] - Address: 205 Clinton Blvd, Clinton, Mississippi 39056 - Hours: Monday–Friday, 9AM–5PM (but 24/7 support via call/text)
Mid State Firearms manufactures their own uppers in-house and sources OEM Microbest BCGs – they don't resell cheap import components. They're used by AR builders to supply their own assembly operations.
They've built a reputation on three pillars:
1. Fast turnaround – same-day shipping for in-stock items 2. Aggressive pricing – especially on grab bag and blemished inventory 3. Stand-behind-it warranty – they'll swap, repair, or upgrade with no argument, even months after the sale
The reviews speak for themselves: thousands of satisfied customers, and repeat business from people ordering their 3rd, 4th, or 5th upper.
All uppers are assembled and tested in Clinton, Mississippi. They've been in the AR-15 customization business for over a decade, and their focus hasn't wavered.
