Well got a 2 hour slot at the range today to try out my new MDI build.
1 round per mag never was able to hold open.
My first time playing with adjustable gas as well as a gas system other than carbine.
Rifle length gas
MRA 18.6" barrel 223 wylde
Odin works adjustable gas block (set screw version, I did dimple the barrel with a jig)
Armaspec SRS (the carbine version which is the lightest they sell "3.3oz")
Brownells Lightweight BCG (also tried with a AAC BCG which feels allot heavier, didnt hold back)
Nothing on the end of the barrel yet, just bare threads
EDIT: I'm not sure on the proper terminology, but its not a rifle length buffer and its not a A5. Just a typical buffer tube.
Tried with 2 different mags (1 metal, 1 plastic) both functioned 100% in 2 other AR's
Sadly I forgot to bring a normal coil spring/buffer to try swapping out.
The odin has 20 clicks of adjustment. Started at 3 click out, increasing by 3 each shot.
Either at the initial 3 out or at 6 out the bolt would be left slightly not fully forward. (just enough gas to start to push it back?)
Around 12 click out it would eject the brass. But not hold open. 4:30 or 5 o'clock or so.
Ran it all the way to 18 or 19 click out (20 click out feels too loose) It would throw the brass good 3:30 or so, but still never held open.
Did try a mag with 5 rounds in case of issues with the bolt hold open. No different, ejected the round but did not grab the next.
With a empty mag in, pull charging handle back, bolt holds open just fine.
The Armaspec SRS feels like it gets a bit harder right near the BCG being fully back. Is this too much resistance right at the end? Because its a SRS i did not install the buffer retaining peice, which allowed me to thread in the buffer tube maybe one extra rotation. This would ever so slightly add more spring tension.
Rifle length gas and short 18.6" barrel need much lighter weight spring and/or buffer?
Or do all signs point to gas block being off center? Gas block screws are still tight after.
Or is it scared of liberals and trans-gendered to a straight pull bolt action?
Thoughts?
