5. Do you have a break in process?
We recommend cleaning the bore after every round for the first 25 rounds, and then clean bore after ten rounds for the next 100 rounds. Our rifles require “excessive lubrication” on the bolt carrier assembly for proper functioning during break in.

7. Why don't I receive emails from DPMS (order confirmations or special offers)?
Make sure DPMS is in your "Safe Sender" list in your email application. Some corporations/companies may have restrictions set up on their email servers. To avoid having DPMS marked as spam by your corporate email filter, it is best to use your personal email address when ordering.
8. Where can I find the DPMS "No Signature Required" Form?
The "No Signature Required" Form is available at checkout in the store. If you missed it, you can also find it HERE
9. Is there a difference between 5.56 NATO and .223 Rem?
Yes, despite external dimensions being identical, 5.56 NATO ammunition is a higher pressure round than commercial .223. If your rifle is chambered in .223 only .223 should be used as using .556 NATO can create an unsafe high pressure condition. If your rifle is chambered in 5.56 NATO it is safe to fire both .223 and 5.56 NATO.
10. What Ammunition should I use for best accuracy?
Every rifle is different but as a baseline this is what is recommended as a starting point.
5.56/223 1x9 twist 50-55gr (match grade)
308/7.62 1x10 twist 168-175gr (match grade) 168gr match seeming to be the best overall

The specific chambering of the rifle is stamped on the bottom side of the barrel in front of the gas block/front sight.
14. I just bought a DPMS rifle at a gunshow, and want to know if it factory built how can I tell?
We stamp the letter ”K” on the end of the serial number (eg. FH12345K) to indicate a NON factory built rifle. No “K” in the serial number means factory built.
