The DOE pistol line is something else I dig it.
Been running mine with a rare breed FRT and m231 tube.
It runs good.  Runs even faster with a dpms .308 carbine spring has some serous muzzle rise.
Smiles all around
Waiting on my form 1 for a proper stock

During endurance testing we broke a standard hammer pin.

So we so switched to KNS heavy duty 9mm pins.

I love mine.
I put an FRT in it with a Maxim RDB and it cycles around 800 RPM.

They now make the DOE in 300 blackout. It has perked my interest.

Nice.  Which FRT and any other mods with respect to the FRT required?

I have a metal housing Kabuto kit I built with a Maxim carbine RDB.

I was using a KAK Industries K-Spec 8.6oz buffer, it worked well, but would jam every once in a while upon ejection because of extraction turbulence, especially with the suppressor on it.

I want to to put the Partisan Disruptor in it when the new pin kit comes available. I absolutely hate the way the safety lever and the anti walk pins look. I cut my own safety lever for it, but there is a kit coming with internal clips for standard pins.

The Kabuto requires you to cut up the internal bolt weight for clearance, so buy a new bolt and sacrifice with the modifications if you don't go with the Maxim which requires the weight to be removed.

ALso, you will need to file the ejector face flat to match the bolt face. It's beveled from the factory.

The way my Lower is made inside a kabuto won’t fit.
Only the drop in complete style FRT will work and you’ll probably wind up staking some screws or pins because that shelf area is what generally holds the device together.  
The RB FRT I was using shook the trip screw loose I caught it before.  
It’s my fault for using the .308 spring I knew better.

I’m gonna redo the 9mm buffer to eliminate hammer pressure some.

Reviving an old thread cause I'm really wanting one of these . Does anyone who has a 633 know if an Aimpoint gooseneck mount will fit?

I have test fit my AimPoint gooseneck Mount on my H&R DOE and it fits perfectly. I have the one that slides into the top portion of the carry handle and then secures with U shaped bracket and screw. It did look cool but it was way too big with a full size aimpoint. I have since switched to a Daydream defense minimalist mount with a Vortex Venom.

Does anyone know if that front sight block can be purchased by itself? I looked at H&R and PSA but didn’t see just that for sale.

You could try Liemohn's, Garrison or Sherluk for individual parts.  But, be aware PSA's is not the original Colt's barrel size (0.625").  I think there's is 0.750".

Thank you for the help and info. I’m actually looking for the .750 size for a build I’m trying to piece together
