AR-10/DPMS-LR Chambering Services:
We can chamber and headspace an AR10/DPMS-LR style barrel however you must supply us with the bolt so we can properly perform this work. If you are sending a bolt for this purpose we ask that you send the BOLT ONLY (no carrier) and that the bolt be stripped of it's ejector and extractor. This is needed as we spend far too much time dissasembling and re-assembling customers parts. Also, many of the chromed bolts have extremely tight fitting pins causing additional work on our part. The bolts supplied by the customer are YOUR responsibility and we can no longer continue to spend hours every month working on these components.
If you send your bolt assembled and/or with the carrier an additional charge will be added for dissasembly/re-assembly.
If we are performing a complete fitting on your upper, then send your assembled components as always.
Customer supplied Handguards:
With ANY AR10/DPMS (.30 cal style) or AR15 type upper that you send for an assembly: If the handguard or upper you send requires a special tool sold by the manufacturer of that component to assemble it, you must supply us with that tool or we will reserve the right to decline the fitting. We cannot possibly keep up with all of the handgaurds offered by all of the companies that make them, or know what tools are needed until we actually have them in front of us. If there are any questions on whether or not a special tool is needed, please contact the manufacturer of that component BEFORE sending it to us for a fitting.
Please feel free to call us with any questions relating to these barrels.
