Sabre 11.5 buffer/spring for frt
Will be first time putting a frt in a gun and according to my research since my Sabre 11.5 comes with a h1 I need to upgrade it to a h3. But I guess it’s not as simple just ordering the super 43 with there h3 due. So from google I learned I would need this particular buffer and it recommended using the super 42 rifle length spring with it. Would this combo be ideal? Also would I want to go with the h3 or h4? There website suggested h4 just based on the fact I clicked the suppressed option as I do have a suppressor. I have a rifle speed gas block for adjustment. The suppressor is a flow through I’m only setting 6 with it and it’s probably slightly under gassed atm tbh
