I recently did alittle experimenting with buffers just to see what all the fuss was about and ATF recently allowed me to pickup my new suppressor. I wanted to see what worked and what didn't, suppressed and unsuppressed. I was going to post this as a separate thread but....I'm certain nobody wants to see yet another buffer thread.
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 alittle 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?
Scoby
Laws that forbid the carrying of arms disarm only those who are neither inclined nor determined to commit crimes. Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man. Thomas Jefferson, quoting 18th century criminologist Cesare Beccaria in On Crimes and Punishment, 1764
