Common Mossberg 100 ATR Problems & Solutions
Several issues can affect the Mossberg 100 ATR's performance. These problems are often easily resolved with proper cleaning, maintenance, or minor adjustments.
1. Feeding Problems: Failure to Feed or Eject
This is a common issue, often caused by:
- Dirty or damaged magazine: Accumulated dirt, debris, or damage to the magazine spring or follower can prevent smooth feeding. Solution: Thoroughly clean the magazine with a suitable solvent and brush. Inspect for damage and replace if necessary.
- Dirty or damaged action: A build-up of fouling within the action can impede the smooth cycling of cartridges. Solution: Disassemble the action (following Mossberg's instructions), clean thoroughly, and lubricate with a gun-specific lubricant.
- Improper ammunition: Using ammunition that's not compatible with the rifle's chamber (incorrect caliber or ammunition that's too dirty or damaged) can cause feeding problems. Solution: Use only high-quality ammunition that is specifically designed for your Mossberg 100 ATR's caliber.
- Weak magazine spring: Over time, the magazine spring can weaken, failing to push rounds reliably into the chamber. Solution: Replace the magazine spring with a new one.
2. Accuracy Issues: Poor Grouping or Inconsistent Shot Placement
Inconsistent accuracy can stem from several sources:
- Poor ammunition: Using low-quality ammunition or ammunition that isn't consistent in its performance can lead to erratic shot placement. Solution: Experiment with different brands and types of ammunition to find one that groups well in your rifle.
- Improper scope mounting: An improperly mounted scope or loose scope rings can cause shifting point of impact. Solution: Ensure the scope is correctly mounted and tightened according to manufacturer's instructions. Consider using a torque wrench to prevent over-tightening.
- Dirty barrel: A fouled barrel can affect accuracy. Solution: Regularly clean the barrel using a suitable cleaning rod, patches, and solvent.
- Improper shooting technique: Issues like flinching, improper stance, or incorrect trigger pull can severely impact accuracy. Solution: Practice proper shooting techniques and consider seeking professional instruction.
3. Bolt Issues: Bolt Binding or Difficulty Cycling
Problems cycling the bolt can indicate:
- Lack of lubrication: Insufficient lubrication can cause the bolt to bind. Solution: Apply gun oil or grease to all moving parts of the action.
- Build-up of debris: Dirt and debris can restrict bolt movement. Solution: Disassemble and clean the action thoroughly.
- Damaged extractor or ejector: Worn or damaged components can affect bolt function. Solution: Replace the damaged parts (requires gunsmithing skills or professional help).
