Bolt Carrier Group Case for CMMG 22 Conversion and AR15 BCGs (Forest Green)
Best for owners using a CMMG 22 conversion BCG alongside a standard AR-15 BCG. The case is designed to carry both components, enabling quick swaps during range sessions. Its water-resistant construction helps protect components in light rain, though it is not fully waterproof. The kit includes two printed pieces—tube and cap—with a cap hole for add-on paracord. BCG parts are not included, making this ideal for the buyer who already has spare BCGs and wants secure transport.
Who it’s for: shooters who frequently switch between a CMMG 22 conversion and a traditional AR-15 BCG and want a compact, protective case.
Caution: Submersion will allow water in, so use the case as intended for partial weather exposure rather than full immersion.
Bolt Carrier Group Case – Green
This storage option is best for standard BCGs, including simunition variants. It emphasizes a straightforward design meant to protect and transport a single BCG without extra frills. The case is produced in the USA, aligning with buyers who prefer domestically manufactured components. It is a practical selection for the everyday AR-15 enthusiast who wants a reliable, no-nonsense BCG case.
Who it’s for: users needing a dependable, USA-made BCG case for single-BGC storage and transport.
Caution: Not designed for multiple BCGs or specialized conversion bolts; choose this if you only carry one BCG.
Bolt Carrier Group Case for BCGs (Earth Brown)
This version extends the same protective concept to carry an extra BCG. It notes compatibility with Aero, Toolcraft, Radian, and ADM BCGs, but explicitly states it won’t fit the CMMG 22 conversion bolt. The enclosed design remains water-resistant for range trips in light rain. Its simple two-piece construction—tube and cap with a paracord hole—keeps things lightweight for field use.
Who it’s for: buyers who want an additional BCG in a travel-friendly case for commonly used brands.
Limitation: CMMG 22 conversion bolts are not supported; verify your BCG brand before purchase.
2 Pieces M16 Male Thread Machinery Shoulder Lifting Ring Eye Bolts
Best for projects requiring sturdy M16 hardware, these bolts are made from 304 stainless steel with a 16 mm thread and a 35 mm ring inner diameter. They’re suitable for a range of mounting and lifting tasks. This choice aligns with buyers who want reliable hardware for maintenance and DIY builds, particularly when integrating M16 components into a larger system.
Who it’s for: builders and DIY enthusiasts needing durable M16 fasteners for various assemblies.
Caution: Ensure proper engagement with mating components to avoid loosening under load.
Hard-to-Find Fastener 014973173371 Class 10.9 Hex Cap Screws
These hex cap screws measure 16 mm in diameter and 80 mm in length, categorized as Class 10.9 steel, offering high tensile strength. While not BCG-specific, they serve as robust fasteners for various assembly tasks in firearms-related projects and shop repairs. This pick is best for buyers who need heavy-duty hardware for critical connections and DIY builds that require high-strength fasteners.
Who it’s for: users needing specific-length, high-strength fasteners for firearm maintenance and other demanding tasks.
Caution: Verify thread compatibility with your intended application to ensure proper engagement.
uxcell M16-2x50mm Hex Serrated Flange Bolts
Similar to the 60 mm variant, this 50 mm option provides a compact solution for M16-2×50 mm hex flange bolts in DIY projects or fixes around the home and shop. Made from 10.9 grade carbon steel with a black oxide finish, it offers high strength and corrosion resistance. It’s best for buyers who need slightly shorter bolts for specific assemblies where space is constrained.
Who it’s for: DIYers needing reliable, shorter M16 bolts for various assembly tasks.
Caution: Confirm length and flange dimensions match your application before purchase.
Buying Guide: How to Choose the Right M16 BCG Accessories
- Purpose and compatibility: If you use a CMMG 22 conversion, prioritize cases designed for dual compatibility. For standard BCG storage, a single-BGC case may suffice.
- Weather and transport needs: Water-resistant is useful for range days with weather exposure; fully waterproof cases are better for harsh environments.
- Material and build quality: Look for USA-made or domestically sourced components when possible for reliability. Stainless steel and high-grade carbon steel offer durability for hardware.
- Quantity and capacity: Decide if you need storage for a single BCG or multiple BCGs. Some products explicitly state compatibility limits; use them to narrow choices.
- Additional features: Paracord-ready caps, internal separators, and simple assembly design can improve on-field usability and ease of transport.
