Gunsmith Near Riverside

[Topflight80]

I just put together a pistol upper last night in 300 blackout.my question is does anyone know of a gunsmith in the riverside area that can check the headspace I also have a .223 upper I would like to have checked out for headspace.

I can give you a good tip, with the upper off, have the bolt closed and if the back of the BCG is flush with the back of the upper receiver I heard you close to money there, if it seats inward or outward you got problems. ( I did this with my .223wylde barrels with 5.56 bcgs)

However, do not rely on this completely it is still recommended that you bring it to a professional gunsmith to be worked on.

^^^^^^^^^^^^^^^^^^^
Please don't believe the above.
Find someone that has the gauges.

The back of the bolt carrier has absolutely nothing to do with headspace. Gauges are the only correct way to check.

Okay well then I have some words to be had with someone about what I was told...

I know you need gauges I'll problably end up buying them I just didn't want to wait on shipping and all that I want to shoot this thing took me 2 years to finally put it together

False.
This test tells us absolutely NOTHING about the headspace.

I charge $10 to check headspace.
I have gauges for about 60 different chamberings.
