If the goal is to own and shoot (or display) a real C96, buying and refurbishing a genuine specimen is almost always the better route than building one (Vol 1 §1.4). The C96 is widely available on the collector market; this volume covers acquiring the right one, assessing it, and bringing it back to safe, presentable condition without destroying its value.

Legal posture for owning/transferring a real C96 — antique vs C&R, shipping, the shoulder-stock pivot — is Vol 11. Read it before buying. This volume is the mechanical work.

7.1 Choosing what to buy

Decide the goal first, because it changes the target:

• Shooter: prioritize a sound bore, correct headspace, a solid (not cracked) bolt and lock parts, and a 9×19 Red 9 or a 7.63 in good mechanical health. Matching numbers matter less; condition and safety matter most.
• Collector/display: prioritize matching numbers, original finish, correct variant features (Vol 4), and provenance. Resist the urge to shoot or refinish it.
• Prop donor (for the DL-44 etc.): the opposite logic — a mismatched, refinished, or already-modified gun, or a copy, is the ethical thing to modify (Vol 4 §4.5).

Sources: C&R-eligible dealers, the major auction houses (Rock Island, Morphy), and the collector forums. Verify the variant and serial against a reference (Vol 5) before paying — copies (Astra, Chinese) and rebarreled/reworked hybrids are common and shouldn’t command Mauser prices.

7.2 Incoming inspection

On a candidate or a just-acquired gun:

1. Confirm what it is — variant, serial, markings, caliber (Vols 3–5). Establish the antique-vs-C&R status and document it (Vol 11, ../00-inventory/_TEMPLATE.md).
2. Bore & chamber — light, rifling sharpness, pitting; chamber for the marked caliber (do not assume — Export/Red 9/7.63 all exist).
3. Headspace — check with go/no-go gauges for the chambering before any live fire. The C96 headspaces on the case (mouth for 9×19, shoulder/case for the bottleneck rounds).
4. Lockwork health — hammer/sear engagement crisp, safety functions for its era-type (Vol 6 §6.4), no cracked lock frame or bolt, firing-pin and springs intact.
5. The takedown-latch interlock — confirm the latch only rises with the hammer cocked and the hammer can’t reach the pin with the latch open (Vol 2 §2.6, Vol 6). This is the safety that matters most on a rear-loading action.
6. Matching numbers — record every numbered part (Vol 5 §5.4) before any work.

7.3 Refurbish — what to do

• Detail strip following the no-pin takedown sequence (Vol 6 §6.3); clamp the frame in a padded vise for the mainspring/rocker steps.
• Clean and de-rust conservatively — preserve original bluing and patina where it has value. Light surface rust comes off with oil + nonabrasive methods; don’t take steel wool to an original finish you intend to keep.
• Replace worn/missing small parts with correct ones (springs, firing pin, extractor). Sourcing: Numrich and the specialist C96 parts dealers (../blueprints/README.md §4 lists the Numrich schematic + parts list).
• Fit replacements — extractors and firing pins often need hand-fitting; the C96 is a fitted gun, not a drop-in one.
• Function check then, only if it’s a shooter and headspace is correct, a careful live-fire workup with standard-pressure ammunition. No +P in a vintage action (Vol 3 §3.5, Vol 12).

7.4 Refurbish — what NOT to do

1. Don’t grind or re-stamp markings. It tanks collector value and is legally fraught (Vol 10 §10.6, Vol 11).
2. Don’t over-restore a collectible. A correct, honest, original-finish gun is worth more than a reblued one. Refinish only a gun that is already a shooter/parts-grade piece.
3. Don’t force the takedown. Wrong-order or forced disassembly breaks the interlocking parts (Vol 6 §6.3).
4. Don’t shoot it until headspace and lockup are verified. And never fit a shoulder stock without understanding the SBR pivot (Vol 11).
5. Don’t “improve” it into a different NFA category — no select-fire parts, no stock that turns it into an SBR without the paperwork (Vol 11).
