FT-12 / FT-50 Rear Bolt Part Numbers (Including Lite Versions)
If you’re rebuilding or servicing a Tippmann FT-12 or FT-50, the “rear bolt” part number can be confusing because some diagrams list older or incorrect TA numbers. This post consolidates the correct rear bolt part numbers for the FT-12 (68 cal), FT-50 (50 cal), and their Lite variants—plus the known diagram callout errors.
Quick Summary
- FT-12 and FT-50 (non-Lite) share the same rear bolt: 11636-TA45107 (R10458).
- FT-12 diagram incorrectly shows TA45022 (likely an older/superseded number).
- FT-12 Lite diagram incorrectly shows TA45091; the correct part is TA45216.
- FT-50 Lite rear bolt is 77451-TA45207 (R14164) and is listed correctly.
Rear Bolt Reference Table
| Model | Correct Rear Bolt | RPN | Diagram Listing | Notes |
|---|---|---|---|---|
| FT-12 (68 cal) | 11636-TA45107 | R10458 | Incorrect – shown as TA45022 | TA45022 is likely obsolete or a superseded number. FT-12 and FT-50 used the same rear bolt prior to the Lite versions. |
| FT-50 (50 cal) | 11636-TA45107 | R10458 | Correct | Same rear bolt as FT-12 prior to the Lite versions. |
| FT-12 Lite (68 cal) | 77460-TA45216 | R03541 | Incorrect – shown as TA45091 | Correct part is TA45216. |
| FT-50 Lite (50 cal) | 77451-TA45207 | R14164 | Correct | — |
What’s Actually Going On With the Diagrams?
Parts diagrams are often assembled from prior revisions, and it’s common for a TA number to persist in documentation even after a part is updated or superseded. In this case:
- The FT-12 (non-Lite) rear bolt should be TA45107, even though the diagram shows TA45022. That may indicate an older part number that was replaced/updated.
- The FT-12 Lite rear bolt should be TA45216, despite the diagram listing TA45091.
- The FT-50 and FT-50 Lite diagrams appear to be correct for these specific rear bolt callouts.
Service Tip
If you’re ordering parts for repairs, use the “Correct Rear Bolt” column above as the source of truth. If you’re cross-referencing older documentation or diagrams, the “Diagram Listing” column will help you spot mismatches before you order the wrong item.
