Drill and pin low-pro gas blocks in place

Rated 5.00 out of 5 based on 1 customer rating

Categories/Brands: ,


The service/fee is for a single straight (not tapered)pin. Some of the larger bore calibers(.458 and such) do not allow enough room to safely pin gas blocks. The block will be aligned with the gas port, which is not always perfectly centered.  All you need to send is the barrel and gas block. You can send a complete upper, but a disassemble – reassemble fee may apply if the gas block is not accessible. If you include your barrel nut we will be happy to slide it on before pinning the gas block. Turn around is about a week.


If you don’t submit your order, the work will NOT get done. Do NOT send anything without submitting an order online first.

    I have had this service done to 3 of my barrels by ADCO and every time they have done excellent work. The work is high quality and I have never had an issue. Steve is awesome, always helpful and quick to answer any inquiries. I highly recommend them for your gunsmith needs. I will continue to use them as my preferred choice.
