ProMag drum magazines are an affordable way to increase the capacity of your AR-15 for those long days plinking at the range. The DRM-A8 is a 65 round drum magazine designed for 5.56 ammunition and AR pattern rifles. It is made from a durable polymer with metal inserts and feed lips to withstand the spring pressure of a fully loaded mag. The reinforced feed lips and magazine catch ensure reliable function and a positive lock every time you insert a new magazine. This ProMag drum magazine uses a winding mechanism on the front to reduce or increase follower spring tension whether you are loading ammunition or shooting it. This 65 round 5.56 drum magazine is a great option for those at the range who don’t want to constantly stop to reload.

  • Durable polymer construction
  • Metal feed lips and Magazine catch lugs
  • 65 round capacity of 5.56x45
  • Front winding spring to reduce and increase follower tension

ProMag Industries is dedicated to the quality that goes into their magazines and accessories. Dependability isn’t taken for granted. It’s built in.

Nice product but...

by -

It's a really nice product but it fits very very tight in the magwell and it makes it hard to remove in many lowers that I've tried it in.

Worst magazine I have ever used.

by -

This was the worst magazine I have ever used in my life. I bought three of them and I returned all three. ProMag needs to write me an apology letter for this insult.
<br>We were happy to get this issue taken care of. Please let us know if we may help you on anything else.

Purchased online great price but haven’t had time to use it -it was a challenge to load

Poor quality control.

by -

Too tight in well to use. Returned to Primary once and received more magazines that cannot be used. Returned directly to Promag and received more that could not be used. Just sent back to Promag again. They are supposed to test before sending back this time. Does not fit S&W, Radical, Bushmaster or Colt. Forums are saying file/sand to fit. But Promag would not say how that would effect warranty.
<br>PA reply : We are sorry to hear you had this issue, but it's great to hear the manufacturer is working with you on a resolution.

Will not load round into chamber

by -

When bcg comes forward, the front of bullet does not lift to slide into the chamber so it jams.
