Flex Your Guns Photo Contest: Entry #8

  • 8.5 inch barrel
  • MP5 collapsible stock
  • original HK53 4-prong flash hider
  • Surefire MP5 rail
  • Surefire rail covers
  • UTG tactical light w/quick detach mount
  • HK vertical grip
  • Gear Sector Rail Mount Handstop

Here’s what he has to say:

When I made the decision to build an SBR, I knew I wanted something more unique than but just as cool as an AR or and AK.  Enter the Vector 53 SBR.  The Vector 53 is a clone of the HK53 carbine.  It is just like an MP5 but instead of 9mm it fires 5.56 NATO.  It is a well balanced weapon and weighs about the same as an AR with a 14 inch barrel.

It is a very robust design that uses the same roller delayed blowback system as the famed G3 rifle and MP5 submachine gun. The primary advantage of roller-delayed blowback is the simplicity of the design compared to gas or recoil operation.

Vectors can be hit or miss so I had it refurbished inside and out by and HK gunsmith.  Now I would stake my life on it.  The work done on it includes a lightened trigger, internal polishing of the receiver, new front sight post, and refinishing of the bolt carrier group.

One thing that takes some getting use to is that there is no bolt hold open upon firing the last round.  The click of the firing pin on an empty chamber is the only indication you get.  When that happens, rack back on the charging handle, slap a new mag in, and give the charging handle the trademarked HK slap that shows you mean business!  I love the heads that turn whenever I do this at the range!


I love seeing different kinds of SBRs, and I appreciate DJ submitting his Vector 53 for the contest. I’ve always been a fan of the HK style collapsing stock and while I never got to put one on the CETME I owned due to incompatibility, I also appreciated the “HK Slap!”

Keep DJ’s build in mind when we vote on the top submission on May 29, 2014.
