Frequently Asked Questions

  1. When will my order ship?
    Typically, in stock items will ship within 7-10 business days from point of order. Certain items like barrels, assemblies or complete rifles have longer lead times from a few weeks to a few months or longer.
  2. Does DPMS make airsoft guns?
    No. DPMS does not manufacture, sell or repair airsoft guns. We do license our logo to be used on a line of guns produced by Palco Sports. If you have an issue with an airsoft gun with a DPMS logo on the side, please contact Palco Sports at http://www.palcosports.com.
  3. How can I purchase a short barrel (under 16")?
    Since DPMS does not manufacture AR15 pistol lowers, we have made the decision that we will not sell short barrels or uppers to the general public. To purchase a short barrel for your pistol lower, you will need to contact an FFL holder to have them place the order with DPMS.
  4. How do I become a DPMS Dealer?
    You can call DPMS and speak to one of our Sales Representatives. They will create a dealer account after they receive a copy of your FFL via fax or email. Once your account is set up (usually within 48 hours) you will be given a Username and Password to log into the DPMS Online Store. Once logged in, you will have access to Dealer Pricing on all products in the store with no minimum purchase necessary. If you have a PDF of your FFL you can email it to office_admin@dpmsinc.com to get set up as a dealer as well.
  5. I just ordered a rifle, why is my "Confirmation Email" blank?
    In most cases, a blank confirmation email is caused when a retail customer ignores several prompts advising them that ordering a rifle or lower receiver is not possible online. DPMS does not sell restricted items to any individual without a Federal Firearms License. DPMS recommends printing your rifle summary page and brining that print out to an FFL dealer to place your order. If you are a Registered FFL dealer with DPMS, please contact the sales staff about any blank confirmation emails.
  6. Are there restrictions on shipping for new customers?
    Yes, for first time online customers, the only "rush shipping" available is 3 day. Due to company policy we cannot ship orders from first time customers any faster.
  7. Where is the Cryo-Accurizing Upgrade?
    DPMS no longer offers Cryo-Accurizing for our barrels. The time involved to complete the treatment process is delaying delivery of rifles to the point that we no longer felt it was a benefit to our customers. We may bring it back at some point in the future, but at this time there is no plan to do so.
  8. Does DPMS have a newsletter or online specials?
    Yes. To subscribe to our email newsletter/special offers, send your email address to dpmsadmin@dpmsinc.com.
  9. What is your break in process?
    We recommend cleaning the bore every round for 25 rounds and every tenth round for an additional 100 rounds. Use a bore brush or bore snake with either CLP or solvent.
  10. Will my .223 upper or lower work with a .308?
    We have 2 basic rifle platforms and a few different calibers that correspond with one or the other:

    .223/5.56 Platform: .204 Ruger, .223 Remington, 5.56x45mm NATO, 6.8 SPC, 7.62x39mm and .30 Remington AR
    .308 Platform: .300 SAUM (discontinued), .308 Winchester, .243 Winchester, .260 Remington, .338 Federal and 6.5 Creedmoor
  11. Do you still offer the 22LR or 300 SAUM?
    DPMS no longer offers the .22LR upper receiver. We have also discontinued the .300 SAUM.
  12. Why can't I log in using my previously created account information?
    This may be one of a few simple issues. When logging in using your email and password (or user name and password for dealers) be sure to click the "Sign In" button. Incidentally, hitting "Return" or "Enter" after filling in these fields will conduct a search in the DPMS Online Store with no results, bringing up a page stating "Nothing could be found...". If you have tried this already, make sure your "Caps Lock" is turned off as the passwords are case sensitive, also, when using the number pad, make sure your "Num Lock" is on. One final "quick fix" may be the need to simply update your browser to the newest version. If you are still having problems, please contact us.
  13. 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.
  14. Where can I find the DPMS "No Signature Required" Form?
    The "No Signature Required" Form is available at check-out in the store. If you missed it, you can also find it HERE.
  15. How can I get export information?
    All Export info is available below:
    Export Sales:
    Adam Ballard
    Phone: 320-345-9223
    Fax: 320-345-9249

  16. Are your barrels chrome-lined?
    DPMS offers chrome-lined barrels in the following configurations as a factory option:
    20" Heavy Barrel
    16" Heavy Barrel
    16" M4 Contoured Barrel
    14.5" M4 Contoured Barrel
    11.5" Short Barrel
    7" Short Barrel
    Cost of this upgrade is $32.95. As a note ALL 14.5", 11.5" and 7" barrels have chrome-lined bores and chambers.
  17. What chambers are used in DPMS AR15 barrels?
    To determine the chamber of your DPMS barrel, look to the underside of the barrel forward of the gas block/front sight base for the chamber stamp. This stamp will give your rifle's actual chambering along with the twist rate of the barrel. DPMS currently produces barrels chambered in .204 Ruget, .223 Rem, 5.56x45mm, 6.8 SPC II, 7.62x39mm, .243 Win, .260 Rem, .308 Win, .338 Fed and 6.5 Creedmoor. The 300 SAUM has been discontinued.
  18. What types of lower receivers does DPMS offer for the AR15?
    DPMS offers a forged aluminum lower receiver for AR15s that has been hardcoat anodized per Mil-Spec and Teflon coated black. This process provides more wear resistance and provides a color match between our upper and lower receivers. We have discontinued stainless steel and cast lowers.
  19. I just bought a DPMS rifle, or at least I think it is a factory built DPMS rifle. What markings indicate if it is factory built?
    The serial number on a factory built DPMS rifle WILL NOT have a "K" at the end of the serial number. The "K" indicates that the lower receiver was sold separately and is therefore not considered to be a complete rifle.
  20. My DPMS post ban rifle has a compensator on it, can I remove it?
    No, DPMS permanently attaches the compensators to post ban rifles and if removal is attempted severe damage to the rifle will result.
  21. How can I find out when my rifle was built or what model I have?
    Click here to request the date of manufacture or the model ID of your rifle. Be sure to send your complete serial number off of your lower receiver.
  22. How can I tell the difference between a pre ban and a post ban configuration?
    A pre ban configuration will typically have a threaded muzzle, a bayonet lug and a collapsible stock. A post ban configuration will have none of these features.
  23. Is it illegal to use M-16 parts in my AR-15?
    Yes.
  24. What types of magazines are available for the RFLR-308 line of rifles?
    All rifles in the LR-308 series now ship with two (2) 19 round steel magazines, or two (2) 10 round steel magazines dependent upon your local firearms restrictions. We also carry a 4 round "Hunting" mag for the .308 as well.
  25. Do other magazines work in the LR-308 line of rifles?
    Yes, the original AR-10 Stoner waffle 20 round magazines and the Knights Armament SR-25™ 10 & 20 round magazines will also work.
  26. What other calibers for the LR-308 do you offer?
    At this time DPMS offers the .300 Rem SAUM (discontinued), a .260 Remington, a .243 Winchester, a .338 Federal and a 6.5 Creedmoor as alternative options to the .308 Winchester.
  27. Do you charge for shipping?
    Yes, however all ONLINE RETAIL orders over $50 receive free UPS Ground shipping (Excludes Alaska and Hawaii).
  28. Are the upper and lower assemblies of the LR-308 line of rifles interchangeable with other manufacturers rifles? (For example: Can I put a DPMS LR-308 upper assembly on an Armalite® AR-10™ lower assembly?)
    No. The assemblies for the DPMS LR-308 line of rifles are proprietary and will not interchange with other .308 caliber rifles except the Remington R-25 without gunsmithing.
  29. Will AR-10 handguards and rail systems fit on the LR-308 line of rifles?
    No. The AR-10 has a different thread pitch on the barrel nut and upper receiver.
  30. Do you have iron sights available for the LR-308?
    Yes, standard AR15 flip-up and detachable sights work with the LR-308 series of rifles.
  31. What does DPMS stand for?
    DPMS stands for Defense Procurement Manufacturing Services.
