  1. RDB Bullpup Rifle
    Trying to think of solutions to the accuracy issues reported with RDB rifles. Given that putting pressure on the handguard seems to be the biggest problem (especially with a bottom-attach bipod) I'm wondering if suspending the rifle from an over-bore bipod would be an improved way to support the...
  2. RDB Bullpup Rifle
    I'm left handed and whenever I'm trying to disengage the safety on the RDB-C I have to move my left hand significantly to ensure that I have pushed in the button all the way from the right side of the rifle, otherwise the gun will "fire" with the hammer only falling halfway. I have this happened...
  3. RDB Bullpup Rifle
    I picked up my new RDB last week, and haven't fired or disassembled it yet. However while familiarizing myself with it and it's operation I've noticed that given a slight bit of pressure the forend will audibly "click" forward or backwards about 1mm. I've made sure that all the bolts are tight...
  4. RDB Bullpup Rifle
    I just gotten my hands on my RDB-C and I has a few questions about the receiver. Has anyone gotten any surface rust on their receiver from direct hand contact? And what about heating issues? The receive seems to get pretty warm after a hundred rounds with a slow rate-of-fire. I am just wonder...
  5. RDB Bullpup Rifle
    Notice the "ring" on the ejected shell? It was made by the bolt head. The area around the hole for the firing pin is raised like a volcano. I have reached out to KT on this but I haven't heard anything yet. I have never seen anything like this, the M4A1 bolt head is flat, so was the M16A2...
  6. RDB Bullpup Rifle
    Here in the Bay Area CA we were graced by a nice 75 degree sunny day on the first day of the weekend, since many range has started to reopen I decided to take out my RDB-C and zero it with holosun HS503G-ACSS. Here is some experience I would like to share from the range visit. Ammo: American...
  7. RDB Bullpup Rifle
    Since I purchased my first rifle just before the global pandemic took place. I have been slowly getting it set up to my heart's desire. Today the last piece finally went on the rifle and here it is: Loaded with 10 rd Pmag With GI mag (10 rounds blocked) Loaded weight with 10rd Pmag...
  8. RDB Bullpup Rifle
    I guess the C stands for #ChangeMyMind since I never though guns have sex, I think my RDB-C is a boy. Jokes aside, look at this What function does it serve? I measured it and it is about 18mm across, almost 30mm long, and 8mm tall. This is the spec diagram of a regular NATO rail (very close...
  9. RDB Bullpup Rifle
    Hi all, I'm a new owner of RDB-C. Full disclosure, this is my first personally owned rifle and yes because I live in CA and this is the only rifle I can grip comfortably and won't break a hole in my pocket to buy. I'm in the USAR and have been issued and shot both M16A2 and M4A1. The main...
  10. RDB Bullpup Rifle
    Hey all, I recently received my RDB raptor rail from Lucky Irishman and was hoping to attach it to my RDB-C. I had seen a pic of a "C" with the rail and thought it would be an easy install like a normal RDB. Turns out, things are just out of reach. Hoping I could get some suggestions...
  11. RDB Bullpup Rifle
    I purchased a black RDB-C last year, and I'm very happy with it. It came with the mag release on the right side only, which can be a pain. Lately, I've been seeing videos and pictures of RDB-Cs with an ambidextrous mag release. Can anyone tell me if this a kit that can be purchased, or is it...
