Are CMMG lower parts kits any good? The short answer is: yes, generally. CMMG has built a solid reputation in the firearms industry, and their lower parts kits reflect that. However, a more detailed answer requires understanding what makes a good lower parts kit and how CMMG stacks up against the competition. This review will explore the quality, features, and value of CMMG lower parts kits to help you make an informed decision.
What to Look For in a Lower Parts Kit
Before diving into the specifics of CMMG, let's establish what constitutes a high-quality lower parts kit. Key factors include:
- Material Quality: The components should be made from durable materials like hardened steel and high-impact polymer. Cheap materials can lead to malfunctions and premature wear.
- Manufacturing Precision: Precise machining ensures proper fit and function. Loose tolerances can cause feeding issues or even prevent the firearm from functioning correctly.
- Component Completeness: A good kit includes all necessary parts: trigger, hammer, disconnector, safety selector, etc. Missing parts are a major inconvenience.
- Finish: A durable finish protects against corrosion and wear. Look for hardcoat anodizing or other reliable surface treatments.
- Reputation of the Manufacturer: Choosing a kit from a reputable manufacturer like CMMG reduces the risk of receiving subpar components.
CMMG Lower Parts Kit: A Detailed Look
CMMG lower parts kits generally score well across these criteria. They're known for:
- Reliable Materials: CMMG utilizes quality materials in their manufacturing process. While they might not use exotic materials, their components are consistently made to meet or exceed industry standards.
- Consistent Manufacturing: Their manufacturing processes are designed for consistency, reducing the chance of receiving a defective part. This translates to reliable function.
- Complete Kits: CMMG kits usually include all the necessary components for assembly, minimizing the need to source parts from other suppliers.
- Durable Finishes: Their parts typically feature a durable finish designed to withstand the rigors of use.
Potential Drawbacks
While CMMG kits are generally well-regarded, it's worth noting a few potential drawbacks:
- Price Point: CMMG kits often fall in the mid-range price bracket. You can find cheaper options, but those may compromise on quality.
- Minor Variations: Like any mass-produced product, minor variations in finish or tolerances might occur. This is usually insignificant and unlikely to impact functionality.
CMMG vs. The Competition
CMMG competes with several other reputable manufacturers of lower parts kits. While a direct comparison requires testing various brands side-by-side, CMMG generally holds its own in terms of quality and reliability. The choice often comes down to personal preference and budget.
Conclusion: Are CMMG Lower Parts Kits Worth It?
For most builders, a CMMG lower parts kit represents a solid investment. They offer a balance of quality, reliability, and completeness without breaking the bank. While slightly more expensive than some budget options, the potential for malfunction or incompatibility with cheaper kits outweighs the price difference. If you're looking for a reliable and dependable lower parts kit for your AR-15 build, CMMG is a worthy contender. Always remember to consult with a qualified gunsmith if you're unsure about any aspect of the assembly process.
