AR-15 7.62x39 Complete NiB QPQ Bolt Assembly

---

• Bolt Face is .125" recess 
• Bolt body produced from AISI 9310 VAR (Vacuum Arc Remelt), the highest standard bolt material made
• Melonite
• HTP/MPI test, our material is checked prior to machining by our supplier of 9310
• Machined completely in one operation; this eliminates tolerance and repeatability issues that arise from multiple fixturing processes used by other manufacturers
• Enhanced Design for utmost reliability
• Tightly controlled proprietary heat treat process to accurately control cast depth and core hardness
• NSCW Crane Division extractor upgraded with Viton® O-ring, 5 coil spring, and plunger
• Extractor produced from MIL-S-5000 Steel
• Extractor Produced from MIL-S-5000 Steel
• Vacuum Hardened
• Machined
• Phosphate
• We choose phosphate extractors to prevent the NiB lubricity properties that can increase slippage off the casing

PLEASE NOTE: Tula Ammunition and Golden Tiger have issues where some primers are set too far in and will still cause light strikes even with an Enhanced Firing Pin 

• For this reason, we highly suggest sticking to steel cause ammunition such as Wolff or Silver Bear
• If you continue to have light primer strikes with Enhanced Firing first check your hammer spring to ensure it is installed properly.

THE 3 MOST COMMON THINGS THAT CONTRIBUTE TO PREMATURE EXTRACTOR FAILURES:

• Tula Ammunition and Red Army are extremely hard on 7.62x39 bolt assemblies and extractors. We have tested this particular brand on many occasions and have found that cartridges tend to get stuck and/or casings do not shrink properly which causes undue stress on the extractors and the bolt lug next to the extractor. This will contribute to premature failures of these parts. 

• Overgassing! Overgassing is another issue we see most common in premature bolt assemblies and extractor failures. To prevent premature part failures, the 7.62x39 best performs with a 4 pm ejection pattern (from a shooter's perspective looking at the ejection port as if it were a clock 12 pm to 6 pm). If you are at a 2 pm to 3:30 pm for ejection pattern you are overgassed with this caliber. To slow down the bolt carrier you can use a heavier buffer such as an H2 to get your ejection pattern as close to 4 pm as possible as this allows for the casing to shrink further before extraction takes place thus reducing the stress of the bolt assembly and/or extractor.

• Barrel Extensions with a large wide single feed ramp with no middle lug does not support the bolt assembly properly.

WE HIGHLY RECOMMEND WOLF AMMUNITION FOR THIS CALIBER
