This video details a comprehensive safety and function test of a newly cleaned SKS rifle, highlighting significant bore and chamber issues that required extensive remedial work. The instructor demonstrates a cautious approach to the first live-fire test, utilizing remote firing and a Lead Sled due to the firearm's condition. The process includes detailed borescope inspections before and after firing, assessing the impact of light loads on brass extraction and case integrity.

Quick Summary

The SKS rifle's bore and chamber presented significant issues, including rust, pitting, and flaking chrome lining. Extensive cleaning with solvents, brushes, and lapping compounds was required. A cautious initial live-fire test used a light load and remote firing setup, revealing a split neck on the first casing but no further damage after subsequent shots.

Frequently Asked Questions

What were the main issues found with the SKS rifle's bore and chamber?

The SKS rifle's bore and chamber were found to be heavily fouled, rusted, and pitted, particularly in the throat. The chrome lining also showed signs of flaking, and the crown was not in good condition, necessitating extensive cleaning and remedial work.

What cleaning methods were used to address the SKS bore issues?

Aggressive cleaning methods were employed, including various solvents and brushes. The instructor also used JB Bore Paste, JB Bore Bright, and 320-grit Wheeler lapping compound with a drill and mop to remove severe fouling and pitting.

How was the initial live-fire test conducted for the SKS?

Due to the rifle's condition, the initial test involved a light load (22 grains Accurate 1680 with a 123-grain FMJ) and a remote firing setup using a string tied to the trigger, with the rifle secured on a Lead Sled for safety.

What were the results of the SKS function test and brass inspection?

The rifle cycled successfully, and the first casing showed a split neck, but subsequent casings from the same light load did not. Post-fire borescope inspection revealed no significant new damage, indicating the cleaning and light loads were effective.
