Century Arms C308 Problems

1. Inconsistent Ejection Patterns


The issue of inconsistent ejection patterns in the Century Arms C308 could be attributed to several factors. 

One of the most common causes is an improperly installed or worn-out ejector spring. 

This spring is crucial for maintaining a consistent ejection pattern as it provides the necessary force for the cartridge to be ejected properly.

It is advisable to clean the firearm after each use to prevent the buildup of residue and corrosion.

3. Difficulty in Loading Magazines


One of the common complaints with the Century Arms C308 rifle is the difficulty in loading magazines. 

This issue is often attributable to a few factors such as improper alignment of the magazine, broken or weak magazine springs, or even faulty magazine release mechanisms.


To rectify the loading problem, start by inspecting the magazine and its alignment with the rifle. If misalignment is the issue, proper repositioning usually resolves the problem. 

For weak or broken springs, replacement with new, robust springs is often the answer. If the problem persists, it might be due to a faulty magazine release mechanism. 

In this case, contacting a professional gunsmith or the manufacturer for appropriate repairs or replacements is recommended.

4. High Recoil Issues


The high recoil issue in the Century Arms C308 is primarily attributed to the rifle’s lightweight design and powerful 7.62x51mm NATO cartridge.

Key takeaway: Excessive heat from rapid-fire can cause substantial wear and tear, potentially leading to malfunctions or damage.


To mitigate overheating issues, it’s recommended to limit rapid-fire sessions and allow the rifle to cool down periodically. 

Additionally, the use of heat-resistant accessories, such as handguards, can help manage the heat and protect the shooter’s hand.

Key takeaway: Limiting rapid-fire sessions, permitting cooling intervals, and using heat-resistant accessories can effectively manage overheating issues.

7. Loose Forend


The loose forend in Century Arms C308 can be attributed to prolonged use, improper assembly, or manufacturing defects. 

This can lead to instability when aiming and potentially degrade the rifle’s performance.


To address a loose forend, dismantle the rifle and reassemble it, ensuring all parts are tightly secured. If the problem persists, consider replacing the forend. 

Ensure to acquire high-quality parts from a reputable supplier for the best results. 

Always remember, that proper maintenance and periodic checks can significantly reduce the chances of encountering such issues.

8. Bolt Carrier Sticking


The Bolt Carrier Sticking issue in the Century Arms C308 is often caused by the build-up of dirt and carbon in the bolt carrier group or the chamber. 

Insufficient lubrication or rough spots in the receiver or carrier can also contribute to this problem.


To rectify this, regular and thorough cleaning of the bolt carrier group is highly recommended. Using high-quality gun oil for lubrication can effectively reduce friction. 

If rough spots are identified, a professional gunsmith should be consulted for smoothing. It’s crucial to maintain the firearm properly to prevent such issues.

9. Trigger Pull is Hard


The hard trigger pull in Century Arms C308 may be primarily due to a heavy hammer spring or an unpolished sear engagement surface. 

This often results in an increased force requirement to disengage the sear and release the hammer, making the trigger pull feel hard.

Key takeaway: A heavy hammer spring or an unpolished sear engagement can make the trigger pull hard.


The solution to a hard trigger pull involves either replacing the heavy hammer spring with a lighter one or polishing the sear engagement surface. 

This will reduce the force necessary to pull the trigger, improving the overall responsiveness of the firearm. 

It is recommended to seek professional assistance to ensure the job is done safely and correctly.

Key takeaway: Replacing the hammer spring or polishing the sear engagement can remedy a hard trigger pull.

10. Unexpected Magazine Release


The cause of unexpected magazine release in the Century Arms C308 is often linked to the locking mechanism of the magazine. 

Over time, this mechanism can experience wear and tear, or become compromised due to accumulated dirt or debris. 

In some cases, the magazine catch may have been improperly installed or manufactured, causing it to fail.


To rectify this issue, first, inspect and clean the magazine and its catch to remove any dirt or debris. If this does not work, the magazine or catch may need to be replaced. 

It is advisable to procure original manufacturer parts to ensure compatibility and longevity. Additionally, regular maintenance and cleaning can prevent such issues from occurring in the future.

11. Complicated Disassembly Process


The Century Arms C308 is notorious for its complicated disassembly process, largely due to its intricate construction and unique design. 

Users often find the disassembly to be a daunting task, especially those unfamiliar with the specific mechanics of the rifle. 

The main cause of this difficulty lies in the unfamiliarity of the design and the lack of clear instructions provided.

Detailed step-by-step manuals or videos could greatly simplify the disassembly process. Considering a professional’s help for the first few times might also be beneficial. 

Furthermore, the manufacturer should consider providing clearer, more detailed instructions to guide users through the disassembly procedure.

12. Rough Feed Ramp


The cause of a rough feed ramp is often related to prolonged use and inadequate maintenance. Over time, the repeated friction of rounds being chambered can wear down the smooth finish, resulting in a rough feed ramp. 

This issue can lead to unreliable feeding and potential jams, affecting the overall performance of the Century Arms C308. 

Prolonged use, combined with poor maintenance, can exacerbate the roughness of the feed ramp and lead to further complications.


The solution to a rough feed ramp involves careful polishing to restore smoothness and allow for reliable feeding. 

This can be performed using a Dremel tool with a felt tip and polishing compound. However, it is crucial to avoid over-polishing as this can alter the ramp’s angle and disrupt the feeding process. 

Regular maintenance and occasional professional servicing can prevent the feed ramp from becoming excessively rough, ensuring optimal performance for your Century Arms C308.

13. Frequent Jamming


The primary cause for frequent jamming in the Century Arms C308 rifle often lies in the use of improper ammunition or a dirty rifle chamber. 

Using subpar or unsuited ammunition can significantly increase the chances of jamming. 

Similarly, a chamber that has not been properly maintained or cleaned can cause the rounds to lodge incorrectly, leading to jamming issues.


To rectify the frequent jamming issue, it is important to first ensure that high-quality, suitable ammunition is being used for the Century Arms C308. 

Consistent cleaning and maintenance of the rifle chamber is also crucial.
