Pros and Cons of Investing in Grendel Bolt and Grendel BCG
If you own a 5.56 or 7.62 AR-15 and are looking to upgrade to the 6.5 Grendel, your best choice is to change the complete upper receiver. However, if you already have it installed, then this section will highlight the pros and cons of upgrading your bolt.
The primary function of the Bolt Carrier Group or BCG, is to push the cartridge into the chamber, fire the primer, eject the fired cartridge, and load a whole new round. In other words, the bolt carrier group is completely responsible for the magic that happens within a rifle. Want to know the pros and cons if you are thinking to upgrade for your 6.5 Grendel? Read on!
Upgrading your 6.5 Grendel has pros and cons include:
A simple factory-made bolt is made from forged steel or aluminium that is prone to breaking or malfunction. Upgrading your bolt will allow you to choose a much stronger alternative. Furthermore, it also reduces the probability of jamming or malfunction. Features like a nickel coating also increase the life term of your BCG with a nitride finish.
Lightweight and Better Recoil
Aftermarket bolt carrier groups tend to be particularly designed to reduce the overall weight of the rifle. However, the low weight results in a lesser recoil and quick cycling of rounds.
Optimal Gas Block
The 6.5 Grendel runs on a different gas pressure and nitride finish, which may cause your 5.56 adhered gas block to crack. Using an upgraded and specific bolt with a durable and adjustable gas block will reduce or entirely remove this problem.
The 6.5 Grendel nitride finish is not a very frequently used caliber, nor is it readily available in popular stores. Spending money on a new BCG won’t be needed if you’re not going to use the rifle pretty often.
The Criteria – How To Pick The Best 6.5 Grendel Bolt Carrier Group
All the items included in this list are complete bolt carrier groups. Which includes all the components, like the firing pin, extractor, and the gas key. This confirms that you don’t have to find and match parts separately. Hence you save some time as well as money.

A durable bolt prevents any malfunction of the rifle and ensures you don’t get stuck in an emergency. All the bolts reviewed here have been made from durable, high-grade metal so they won’t break easily or fracture even with rigorous use.
A great bolt must have a protective finish like Nitride, nickel-boron, or OPQ, to remove problems like rusting and chipping of the bolt material due to issues like moisture and grime. Additionally, a good finish also reduces resistance by making the bolt’s surface a lot smoother. Furthermore, such bolts are easier to clean.
Adjustable Gas Key
An adjustable gas key lets you change the gas pressure inside the chamber. Such an adjustment is often beneficial to modulate the performance and recoil of your rifle.
