Grantham TV - Testing the PSA $300 AR

Introduction

• Objective: Assess the quality and performance of a $300 AR-15 from PSA (Palmetto State Armory).
• Sponsors: Send and Take Images, Sonoran Desert Institute (gunsmithing school), Primary Arms, Mantis (dry fire training device), AAC Ammunition.
• Conflict of Interest: AAC is a subsidiary of PSA, but Grantham assures unbiased reviews.

Testing Methodology

• Goal: To understand the wear and performance of a $300 AR-15 under hard usage conditions.
• Testing Conditions:
  • Using suppressors to increase wear.
  • Running in auto mode to stress the system.
  • Comparisons with higher-end rifles like URGI.

Initial Findings

• Round Count: 2,000 rounds fired.
  • Using 77 grain AAC ammunition.
• Accuracy: Achieved near 1 MOA with an ACOG sight.
• Performance: Capable of making long shots around 550-580 yards.

Mid-Test Observations

• Round Count: Reached 3,000 rounds.
  • Rifle maintains accuracy but shows signs of wear.
  • Noted uneven wear patterns on the carrier.
• Enhanced Testing: Comparison with an SR-15 bolt (high-end rifle).
  • Displayed quicker wear compared to SR-15.

Advanced Testing

• Round Count: 4,000 rounds.
  • Signs of low lubrication and extractor spring failure.
• Accuracy: Maintained 1.5 to 2 MOA.
• Issues: Exhibited inconsistent ejection patterns.

Final Tests

• Round Count: 5,000 rounds.
  • Issues with gas ring wear and reduced gas efficiency.
  • Group accuracy expanded to around 2.3 MOA.
• Inspection by Expert (Phil):
  • Noted uneven wear and machining marks on the bolt.
  • Overall length of carrier and bolt tail measurements within acceptable range.

Conclusion

• Round Count: Over 6,000 rounds fired.
  • Barrel performance declined after 6,000 rounds.
  • Premature barrel wear noted at 6,000 rounds.
• Recommendation:
