We will supply and install a heavy duty locking bolt spring on your NEW Thompson Center barrel that you have just purchased
from HOA before we ship it for the $10 fee listed above.
What is a "locking bolt spring" and why do I need one? Just like the wide specs found on your hinge pin and the springs located in your frame, the locking lug portion of your barrel contains a spring that can be replaced to improve mating between your frame and barrel.
Be sure to check out the other services offered such as trigger jobs, oversized hinge pins, hammer extensions. Receive these additional discounted services while we are in possession of your frame only. Obviously prices will be higher for the services if not performed in conjunction with the trigger job.
