Hello all,
I have a short stroking issue I want some input on.
Backstory: bought a new windham weaponry AR Orc rifle from academy sports 3 weeks ago (commercial buffer tube, carbine)
Put a few hundred rounds thru her perfectly, from cheap steel to 556.
Found a PSA FN upper I wanted and bought it with the intent of building another rifle with the windham upper.
. list:
Windham factory upper 16" carbine.
New Spikes lower
Spikes LPK
Mil spec buffer tube (carbine buffer)
Red barn armory auto BCG
(BCG’s are complete and includes carrier (8620 Tool Steel), carrier key, bolt (9310 case hardened), extractor, extractor spring, extractor pin, ejector, ejector spring, ejector pin, firing pin, firing pin retainer, cam pin, (3) gas rings, and properly staked screws. Carrier and Gas key are chrome lined.)
The gun was having issues with monarch 223 brass 55gr FMC
Once I started using my m855 and m193 it was running perfect.
So, I started thinking and I have a couple ideas.
1. Check the carrier key torque and for leaks.
2. I need to lower the buffer weight. ( can't find one lighter than the carbine buffer)
3. Need to swap the mil spec tube for a commercial one, .5" longer.
4. Leave alone and shoot mil ammo.
What's your thoughts?
Thanks
