A Thousand Times Better Than Synthetic Patches
Pure, natural-cotton, flannel patches hold solvents, soak up crud and crap and get oils into the grooves better than any other kind of patches made. (Not like the synthetic patches, which are less absorbent…they literally slide right over the fouling!) We know you'll like these. So, if you use more than a small box or two of those "other patches" a year, you'll save money and clean a whole lot better with these bulk paks of 1000 natural cotton flannel patches - just like the ones you used to get as a kid. Handy little wipe around the shop, too. Super for oiling, wiping, cleaning, cold bluing, etc., etc.

The unique drum configuration keeps the height of the magazine manageable as well, allowing prone firing and easier storage. Features a paint pen dot matrix for easy marking and the MagLevel system for instant capacity indication. Compatible with a wide range of NATO firearms such as the M4, M16, SCAR MK16/16S, HK416, MR556, M27 IAR, and others.

Strength of a Machined Receiver With Universal Fit of a Forged Lower
Aero Precision’s M4E1 Stripped Lower Receiver delivers the strength and unique looks of a billet machined lower, with the lower cost, lighter weight, and easy parts compatibility of a forged lower. The M4E1 starts as an "enhanced" forging from extra-strong 7075 T6 aluminum that is precision machined to final dimensions for compatibility with all standard "mil-spec" AR-15 parts. As a bonus, the good-looking M4E1 has a streamlined profile, without the chunky appearance of many milled lowers.
Actually, the Aero Precision M4E1 Stripped Lower Receiver is not quite "stripped." Extra benefits include an integral triggerguard, which creates a more rigid, structurally sound receiver than a standard AR-15 lower, and also eliminates the risk of accidentally breaking off a triggerguard tab when working on the rifle. The enlarged triggerguard opening gives extra clearance so you can easily operate the trigger when wearing gloves.
The M4E1 comes with an easy-to-install threaded bolt catch roll pin that eliminates the risk of damaging the lower’s finish during installation (OK, you may be able to still do damage, but you’ll have to work hard at it!). Other features of the Aero Precision M4E1 stripped lower include:
- Flared magwell opening facilitates fast, one-shot mag changes
- Threaded takedown pin detent recess for easy buffer removal without chasing down a flyaway detent!
- Accepts standard mil-spec AR-15 fire control components, pistol grip, buffer tubes & stocks
- Hardcoat anodized to resist surface wear, in Matte Black or Cerakote™ Flat Dark Earth
The Aero Precision M4E1 Stripped Lower Receiver even has a polymer-tipped tensioning screw nestled in the grip tang that you can adjust for a tight, rattle-free fit with the upper receiver. All the benefits of a custom machined lower without the downside!

Replicas of Early .308 AR Hiders from the Late 1950s
The Brownells BRN-10 Flash Hiders are inspired by the two types of flash hider found on early .308 AR-pattern rifles - making them ideal to cap off the business end of your "Retro" battle rifle build.
The BRN-10 Open 3-Prong model replicates the hider found on Sudanese and early Dutch .308 ARs, while the Closed 3-Prong model replicates the hider found on many Portuguese and later production Dutch rifles. What’s the difference? The Closed model is more resistant to breaking if the muzzle accidentally strikes a hard surface (hence the change on the originals). The good news is that either model will give ANY AR-308 rifle a unique appearance - and do an excellent job reducing the fireball coming from the muzzle!
- Machined carbon steel
- Durable, hard black QPQ finish
- 5/8"-24 thread pitch
- Clearance hole: .320" - excellent for .308 rifles, as well as .243 Winchester, 6.5mm Creedmoor, etc.
Both Brownells BRN-10 Flash Hiders come with a modern-day high-tech QPQ finish that is far more durable than the Parkerized or black oxide finishes of the Old Days, yet replicates the matte black / dark gray finish of the originals. Complete your .308 AR battle rifle build with one today!

Purpose-Built for Your Next AR Build
Brownells upped its offerings to custom AR-15 builders with an all-new Brownells Gen 2 Complete AR-15 Upper Receiver, which provides consumers with all of the elements needed to have a fully functioning upper straight from the box.
The Brownells Gen 2 Complete AR-15 Upper Receiver features a standard flattop A3 profile and is built with a standard M4-profile barrel machined from 416R steel. The barrel is surrounded by a free-float handguard measuring 10 inches long and provides M-LOK accessory-attachment points for added customization options. The receiver is machined from 7075 aluminum and features M4-style feedramps and a standard A2 birdcage flash hider.
- Barrel length: 16 inches
- Chambered in 5.56 NATO
- Black finish
- Barrel twist rate: 1:8
As an added benefit to consumers, this Brownells Gen 2 Complete AR-15 Upper Receiver is totally complete, including the charging handle and bolt-carrier group, added extras not often found on upper-receiver offerings. The bolt-carrier group included with the upper features an M16-profile and will not work on Colt AR-15 lowers with a sear block.
The Ideal Big-Bore Bolt Carrier Group
The Brownells Complete .308 Bolt Carrier Group is designed to operate reliably in DPMS LR-308 pattern rifles chambered in .308, .243, 7mm-08, .338 Federal, .260 Remington, 6.5mm Creedmoor, or any other cartridge based on the .308 Winchester. These BCGs are manufactured to the same uncompromising standards as our M16-style BCGs.
Our Complete .308 Bolt Carrier Group has a bolt machined from robust 9310 steel, heat-treated and shot-peened for superb hardness. The carrier itself is fabricated from hardened 8620 steel. Both are magnetic particle inspected (MPI) to make sure there are no hidden microscopic flaws that could lead to premature failure.
- Carrier has forward assist notches
- Extractor is installed with rubber insert and spring
- Gas key screws are torqued and staked
- For use in DPMS LR-308 pattern upper receivers only; NOT compatible with Armalite rifles
You can get the Brownells Complete .308 Bolt Carrier Group with a hard Black Nitride finish that is exceptionally resistant to surface wear OR a Nickel Boron coating (a dull matte silver) that’s even harder and self-lubricating to boot. Both come complete with firing pin, firing pin retaining pin, cam pin, gas rings, gas key, extractor, and ejector installed.
Brownells GunTech™ Note: Unlike BCGs with a traditional Parkerized finish, the carrier on our Black Nitride bolt carrier group is not hard-chromed inside because Nitride is actually harder than industrial chrome plating.
