TDC regulator for Vsr 10, Bar 10. This TDC is designed to facilitate the adjustment of the Hop Up pressure in a more micro metric way, click by click, allowing you a more comfortable and more precise regulation.
For its assembly we will provide you with a template so that it is easier for you to make the hole in the external barrel of the rifle, in this way you will only have to mark where indicated to drill with a 4 mm drill bit.
Once the hole is created, it is recommended to glue it with Epoxy or any strong glue.
For a more secure fit, it will be screwed to the barrel with 2 small side screws.
