As you'll see...I went around the world only to come back to where I was standing to start with. Live and learn I suppose.
For what it's worth.
Firearm:
LMT Complete Lower w/BAD Lever & CTR Stock
BCM Upper, Daniel Defense 14.5” MidLength Barrel & AAC 51T Brakeout Comp
Suppressor – AAC M4-2000
Mags – 30rd PMags (#7)
Ammo – PPU .223 75gr BTHP Match – 5 rounds fired for each configuration
Note: I normally run a BCM FA BCG, Springco CS Blue Spring and an H Buffer for this firearm and have done so through over 2k of ammo with no issues at all prior to getting the suppressor.
Configuration #1 - BCM FA BCG / Springco Blue Spring
Carbine Buffer:
Unsuppressed – recoil was mild, bolt locked back on empty mag, no malfunctions
Suppressed - recoil was mild, bolt locked back on empty mag, no malfunctions
H Buffer:
Unsuppressed – recoil was mild, bolt locked back on empty mag, no malfunctions
Suppressed - recoil was mild, bolt locked back on empty mag, no malfunctions
H2 Buffer:
Unsuppressed – recoil was mild/maybe lighter, bolt locked back on empty mag, no malfunctions.
Suppressed - recoil was mild, bolt locked back on empty mag each time. Three different times, out of five rounds, the bolt stripped a round but the bolt FAILED close completely.
Configuration #2 – LMT Enhanced BCG (std bolt) / Std Carbine Spring
Carbine Buffer:
Unsuppressed - recoil was mild, bolt locked back on empty mag, no malfunctions
Suppressed – recoil was mild, bolt FAILED to lock back on an empty mag. This configuration was tested three times with the same results.
Configuration #3 – LMT Enhanced BCG (std bolt) / Springco Blue Spring
Carbine Buffer:
Unsuppressed - recoil was mild, bolt locked back on empty mag, no malfunctions
Suppressed – recoil was mild, bolt FAILED to lock back on an empty mag. This configuration was tested twice with the same results.
As stated before, I'm back to the BCM BCG, H buffer and Springco blue spring shooting suppressed and unsuppressed without any problems. Right where I started from.
I did take it a little further and bought some PMC Bronze just to see if it would run weaker ammo. It did without any problems.
Also, does anyone notice anything odd about configuration #2 that theoretically I would not have expected? Any thoughts on this?
