Published on March 9, 2024
Duration: 69:29

This comprehensive evaluation from T.REX ARMS details a 5000-round test of the PSA JAKL, focusing on reliability, accuracy, and training methodology. Expert instruction covers breaking down complex shooting courses into isolated drills, identifying and rectifying common malfunctions and component issues like loose barrels and gas block problems, and performing accuracy assessments. The evaluation highlights the JAKL's performance, value, and compares it to traditional AR-15 platforms for training efficiency.

Quick Summary

The PSA JAKL, after initial issues like a loose barrel and malfunctioning gas block were fixed, achieved over 2500 consecutive rounds without malfunctions. While offering good value, its front-heavy balance and recoil make it less efficient for optimized training compared to a standard AR-15.

Frequently Asked Questions

What were the main issues encountered during the 5000-round PSA JAKL evaluation?

Key issues included a loose barrel requiring re-tightening with Loctite, a malfunctioning adjustable gas block that wouldn't hold settings, and significant wear on the bolt lugs and receiver around the ejection port after approximately 2300 rounds.

How did the PSA JAKL perform in terms of accuracy after 5000 rounds?

Despite initial issues, the JAKL maintained good accuracy. A 30-round group with 62gr PMC X-TAC at 100m yielded a 4.7-inch group. Precision tests showed 5-round groups at 100m measuring 1.7 inches and 10-round groups at 4 inches.

What is the T.REX ARMS recommendation regarding the PSA JAKL for training?

While the JAKL offers good value and functionality after fixes, it's considered less efficient for optimized training compared to a well-built AR-15 due to its front-heavy nature and recoil impulse. Thorough inspection of new PSA firearms is recommended.

How was the PSA JAKL's reliability after initial problems were addressed?

After the gas block issue was resolved by disassembly and manipulation, the PSA JAKL ran for an impressive 2500-2600 consecutive rounds without any malfunctions, demonstrating potential reliability once issues are corrected.
