PDX™
Voted BEST OF SHOT 2019 by RECOIL Magazine, the Maxim Defense PDX™ was born from the SOCOM PDW solicitation to meet the demands of the Tier 1 community.
Designed for close-quarter encounters, the PDX™ delivers maximum energy on target in a subcompact platform, measuring just 18.75″ in overall length.
At its core, the PDX™ features the Maxim SCW™ system, a patent-pending design that reduces the stock length to 4″ and includes an integrated BCG with interchangeable buffer weights for optimal performance. Equipped with Maxim’s HATEBRAKE™ muzzle booster, the PDX™ significantly reduces recoil, decreases flash signature, and directs gases and concussion wave downrange, enhancing overall performance.

I love it & still in love with it. This month just completed it having for 2yrs now. Just afraid to add a suppressor do to it’s void warranty policy if even add a Maxim defense suppressor still voids my warranty on my backpack baby. So I’m just gonna keep it simple. So I’m looking into a Daniel defense another 300 BLK but I’m still keeping my baby though.

Don’t be afraid to throw a can on that beauty. She ran just fine for me. A little too much gas blowback, other than that ate through steel also.

Excellent job

A gun this short chambered in 7.62×39 has no business being this accurate. I’m getting roughly 2.5-3 moa shooting bulk red army 124gr I would have been fine with a 6 inch group at 100 yards but this blew that out of the water. Also this thing is butter smooth, I find myself hand cycling this and dry firing while watching TV because it’s just too good.

One of the best AR platform pistols I have ever ran.
I have the 762.39 truck gun and the 300BO for the suppressed side of things and I’m still crazy about both.
It’s awsome when your at the range and everyone comparing their Daniel’s, Sig rats and Honey Holes to wait and see how almost every shooter turns into a kid at Christmas and wants to hold and run my pdx’s
I’ve had several people go out and purchase one or the other because of their shooting experience with mine twins.
Great job MD and please keep it up.
