| 41. | The barrel stops quickly, and the bolt continues rearward, compressing the recoil spring and performing the automated extraction and feeding process.
|
| 42. | As the recoil spring returns to its uncompressed state, it pushes the bolt body backward with sufficient force to cycle the action.
|
| 43. | It features an exposed hammer, a magazine, and a fixed barrel that also acts as the guide rod for the recoil spring.
|
| 44. | A spiral recoil spring is positioned horizontally, directly below the barrel between the parallel guides of the receiver and rails of the breechblock.
|
| 45. | The magazine follower rises to hold the action open while the cross beam at the forward end of the slide compresses the recoil spring.
|
| 46. | This allows these pairs of calibers to be used in the same firearm with only a change of barrel, recoil spring and magazine.
|
| 47. | Some designers handled this problem by making the moving parts of the firearm heavier and made the strength of the recoil spring much greater.
|
| 48. | The TTR also relocated the recoil spring assembly over the barrel and under the handguard, allowing it to have a true folding stock.
|
| 49. | The recoil spring is now free to return its stored energy to the cycle of the weapon by beginning to return the slide forward.
|
| 50. | When the barrel and mechanism reaches the rearmost point in its travel, the recoil springs push it forward back into its normal forward position.
