Based on my personal experience, I highly recommend Aero Precision’s 6.5 Grendel bolt carrier for anyone building a new firearm or looking to replace an existing one, as it offers exceptional quality. It is outstanding and boasts a flawless finish. After firing approximately 500 rounds of both steel and brass match-grade ammunition, I have consistently hit targets at 1000 yards. I paired this BCG with a 20-inch barrel and a Burris optic, and the results have been impressive. Great review!

I currently own multiple .223 bolt carrier groups (BCGs), but only one for my 6.5 Grendel (G) rifle. I plan on purchasing a spare BCG for my new Bear Creek Arsenal (BCA) 6.5G upper, which I believe requires a “type 2” BCG. Would it be possible to use an Aero Precision T2 BCG, or should I opt for a specific brand?
Additionally, I am curious if a .223 firing pin would be compatible with a 6.5G BCG.

To ensure compatibility with your bolt carrier group, confirm the specific type you have and contact a reputable vendor to verify interchangeability within that type. Additionally, check the headspace of the new BCG with your upper to ensure proper fit.

⚠️ When it comes to selecting a BCG for your 6.5 Grendel rifles, it’s important to make sure you choose a BCG that is specifically designed for that cartridge. In the case of the Bear Creek Arsenal 6.5G upper, it’s recommended that you use a Type 2 BCG, which has a longer cam pin slot and a smaller diameter firing pin than a standard AR-15 BCG.

✅ The Aero Precision T2 BCG is a Type 2 BCG and should work well with your 6.5 Grendel uppers. However, it’s always a good idea to double-check with the manufacturer to make sure their BCG is compatible with your specific upper.

❌ As for using a .223 firing pin in a 6.5G BCG, it’s not recommended. The 6.5 Grendel has a larger case diameter than the .223 Remington, which means it requires a larger firing pin to ensure proper ignition. Using a .223 firing pin in a 6.5G BCG could result in misfires or other reliability issues. Therefore, you should always use a firing pin that is specifically designed for the 6.5 Grendel cartridges.

Although I was initially hesitant about lightweight bolt carrier groups (BCGs), my positive experience with the JP LMOS BCG has made me a believer. In fact, I’ve purchased my third one, as I often use adjustable gas blocks (AGBs) and can achieve precise tuning with gas, mass, and buffer spring/buffer weight configurations. This enables me to identify the optimal setup for the ammunition I choose to shoot. While I reserve these BCGs for my non-combat rifles, I appreciate their noticeable difference in weight and excellent performance.

Hi everyone,
I’m looking for some advice on BCGs and buffers for the Grendel. Specifically, do I need a specialized carrier, or will a standard carrier suffice? Additionally, I’m unsure whether a regular buffer will work, or if I should opt for a heavy buffer. I would appreciate any advice or recommendations on this topic. Thank you.

Hello! 👋
1️⃣ To answer your first question, a standard carrier should work just fine with the Grendel. You don’t necessarily need a specialized carrier unless you’re looking for specific features, such as enhanced durability or reduced recoil. A standard carrier should be able to handle the Grendel’s pressure and provide reliable cycling.

2️⃣ As for the buffer, the weight will depend on your specific build and preferences. Generally, a standard buffer should be sufficient for most Grendel builds. However, if you’re experiencing issues with the bolt cycling or recoil, a heavier buffer might be worth considering. A heavier buffer can help to reduce felt recoil and ensure reliable cycling.

📢 Ultimately, the best way to determine the ideal buffer weight for your Grendel build is through trial and error. You can start with a standard buffer and work your way up in weight if necessary until you find the sweet spot that works best for you.
