1. Thorough Inspection:
* Cleanliness: Make absolutely sure the bolt and receiver are meticulously clean and free of oil or grease. Excess lubricant can hinder proper alignment. Use a soft brush and compressed air if needed.
* Damage Check: Examine the bolt and receiver tines for any damage (bent or broken parts). Even minor deformation can prevent proper engagement. If damage is present, repair or replacement might be necessary.
* Parts Identification: Familiarize yourself with a diagram or exploded view of the Model 87A's bolt and receiver. This will help you understand the correct orientation of each part. You can often find these online through gun forums or parts suppliers.
2. Alignment Strategy:
* Gradual Insertion: Don't force the bolt! Start by carefully aligning the bolt's rear with the receiver. Then, gently push the bolt forward, observing how the locking lugs interact with the receiver tines.
* Visual Alignment: Use a bright light and magnification (if needed) to ensure the lugs are properly seated within the tines. They should fit smoothly and snugly without binding.
* Slight Adjustments: If the lugs appear misaligned, try very slight rotations or adjustments of the bolt's position *before* forcing it further into the receiver. A small shift might be all that's needed.
* Work from the Rear: Focus on getting the rear of the bolt aligned correctly before pushing it completely forward.
3. Troubleshooting:
* Bent Lugs: If one or more lugs appear bent, this is a major issue. Attempting to force the bolt could cause further damage. Consider seeking professional gunsmith help for repair or replacement of the bolt.
* Receiver Damage: Similarly, a damaged or bent receiver tine will prevent proper bolt insertion. This also necessitates professional attention.
* Out-of-Spec Parts: If you've recently replaced any parts, they might not be properly manufactured or fitted. Ensure you've used genuine parts or parts from a reputable supplier known for accuracy.
4. Seeking Professional Help:
If you've tried these steps and still can't reassemble the bolt, do not force it. Forcing the parts can lead to permanent damage. A qualified gunsmith is the best option for resolving this issue. They possess the expertise and tools to safely disassemble, inspect, and reassemble the firearm, ensuring its safe and proper operation.
Safety First: Always prioritize safety when handling firearms. Keep the gun pointed in a safe direction, and ensure the firearm is unloaded before attempting any disassembly or reassembly. If you're unsure about any step, seek professional help.
