The TC Hawken went through various changes in its production history. Nothing that had effected its accuracy as has already been mentioned.
Most of the changes were cosmetic in nature. Listed below are some of these that I’m aware of?
1. The earliest model had an iron trigger guard. Was then switched to brass. Not sure of the year?
2. Stock change in the comb area. The early models had a more pronounced comb where it meets the wrist of the stock.
3. one screw nose cap vs two screw nose cap. Again, not sure of year change?
4. Lock bolt escutcheon. Old type had a lip that was sunk into stock to help secure it in place. New type escutcheon had a flat base. Newer type was also slightly taller vs old type.
5. Tang on older model had three screw holes vs two on later type tang. The center screw hole on old type tang was for a peep sight if desired?
6. Furniture which includes: butt plate, trigger guard, nose cap, thimble’s, and lock bolt escutcheon are minutely beefier on later model’s.
7. Breech plug clean out screw absent on newer models.
8. Rear sight? Three variations that I’m aware of.
9. Front sight? Two variations that I’m also aware of.
10. Stamping’s on barrel? Older barrels didn’t have black powder warning stamping’s. Also known as pre warning barrels. Older barrels had various symbols stamped on bottom flat: Heart, Maltese Cross, Star, Letter M with circle around it. These are stamping’s that I’ve personally seen. Not sure what these stamping’s signify? Have heard two different schools of thought. Inspectors stamp, or out sourced barrel from a different manufacturer contracted by TC.
11. Later model barrel also has the word HAWKEN stamped on the right upper flat.
12. Hammer spur change.
13. Tang bolt closest to breech actually screws into trigger guard on later models.
14. Quick Load Accurizor (QLA) is offered on their later model barrel.
In closing: As you can see, there’s been various changes through TC Hawken’s evolution from start to end date of manufacture.
