Hate it or love it, the 6.5 Creedmoor cartridge is here to stay – and if you plan on using it, you might want to consider a truly personalized shooting experience via your own build. Although the utilization of the standard AR10 style platform is what you are gunning for (pun intended), you are more likely to find better luck with upper and lower kits designed as the LR308 – a more universal, widely available, and compatible fit option.
We’ve compiled some of the best 6.5 Creedmoor build kits for your consideration, and to help you narrow down your choices for getting the most out of your favorite caliber round.

Understanding the LR308 vs AR-10
The 6.5 CM was built for long range competition accuracy and serves well for medium game hunting. Designed originally as an answer to the need for a high energy load with a low recoil, it has moved from wildcat cartridge category to common and accessible as its popularity has grown.
Because it was created as a modified .30 cal round, it is most comparable to the .308 Win, and is shot best through an AR-10 style rifle – EXCEPT, what most people think is an AR-10 is more commonly a DPMS LR308. After the original Armalite patent expired it opened the door to other firearm manufacturers to develop their own based off the original, and the DPMS design has become the Universal Mil-Spec leader that is what many people are unknowingly in possession of.
DPMS compatible parts are compatible across many brands, and provide a ton of interchangeability, whereas true Armalite parts are proprietary to their own. Some brands also create proprietary compatibility as well between upper and lower kits, so always be sure to check before committing to the purchase.
What is a Build Kit?
A build kit is the best way to build your own gun from the ground up to ensure you get the parts and details you want for your shooting needs. Kits include most, if not all, the parts you need, and will let you know what is still needed for a complete upper or lower if anything is not included. Most build kits are specific to the upper or lower receiver of the firearm, so you will have to take care to find parts that will fit together. Some may include all you need or want, but this will limit your choices somewhat – although you can always swap out some parts for others if you don’t mind spending the extra money.
Types of Build Kits
If you can score a deal on both the upper and lower as a complete kit to ensure compatibility, that is great, but you still have to put together both receivers for a finished build.
Upper Receiver Kit
The upper is the bulk of the firearm, but cannot fire without the lower – therefore, is not as regulated as the lower (which is considered the actual “firearm” due to the firing mechanism). It contains, amongst other things, the barrel, handguard, gas block and tube, bolt carrier group, charging handle, forward assist (if included), and the rail system set-up for accessory addition.
An important note you need to be aware of when looking to build your upper: the 6.5 cartridge is designed to fire out of an AR-10 or LR308 with a 6.5 CM barrel – which is designed to be a drop-in option for easy conversion. Many complete builds may come with a barrel, but be aware that for a .308 Win, you are required to purchase the barrel separately. Most uppers are complete as well due to the simplicity of the overall design, but are incredibly easy to customize and modify.
Lower Receiver Kit
The lower, as mentioned, is the “firing” portion of the rifle, and includes the serial number as it is considered the actual gun. This kit will typically contain the trigger group, magazine release, buffer tube, safety selector, buttstock, and grip.
What Skills Do I Need Before Building?
Putting together your own buildisn’t an easy task, and at the very least you should have the basic skills of recognizing and knowing what each part does, and how it operates. Basic gunsmithing skills are a must, and you may want to know a local gunsmith for backup and help should the need arise.
Luckily, most build kits are well designed and provide good step by step guides to the parts and their placement, but your own knowledge must be up to par. You’ll also need to supply much of your own basic tools, such as Allen and regular wrenches, and various screwdrivers.
6.5 Creedmoor Building Kit Buyer’s Guide
Once you get looking, you are going to find quite a few different options from which to choose. As mentioned, the true Armalite, AR-10 is very proprietary in how parts match up, so it is best to stick to the same brand and what they suggest. Your most affordable, and easiest to piece together are DPMS compatible parts and will provide you easy-to-match parts for the life of your weapon whenever you want to upgrade or replace a component. Keep in mind some gun manufacturers have their own proprietary fits as well in relation to upper and lower compatibility, although they can generally accept other DPMS parts with ease.
Watch for What Parts are Included
Just because something is labeled as a kit, doesn’t mean it automatically has everything you need, and may simply be a partial collection of specific parts. Be sure to know what you need for either a complete or partial build. There are many kits specific to modification of existing rifles as well, which is often a great starting point for beginners.
Check Brand Names
Be sure to get trusted gun manufacturing brands that offer warranties and parts support. It is tempting to take advantage of off brand and inexpensive names, but a good supplier will be transparent in parts materials, where they are made, and what they offer you for a guarantee and customer satisfaction.
Pay Attention to Compatibility
Another tempting habit is to shop across brands to find the best bang for your buck. There is nothing fundamentally wrong with doing so, but if you are new to this and the overall terminology – you could end up with parts that won’t fit together. Watch for parts compatibility and proprietorship to ensure you don’t waste your money.
Watch the Price Point
Just because the best advice I can give is to stick with tried and true brands and companies that offer transparency doesn’t mean there aren’t some great budget friendly kits out there! Shop around, make lists, and don’t be afraid to ask questions of the company and even a gunsmith to get the best quality deal.
