2016年5月8日 · Our custom 380 barrels, are physically/metallurgical identical to our M11/9 upgraded barrels, except chambered in 380. Materials: 4140 Chrome-Moly steel. Alignment: Bore-OD/Center. Rifling: Button. Twist: 1:10 Chamber: Upgraded (proprietary) from oem specifications & polished for improved feeding and extraction.

2025年2月27日 · I'll throw in American Eagle 90 gr. as another .380 round that has worked well in the small mag M11-380 that I have had for about eight years. That includes shooting with the standard (high ROF) and the tungsten (low ROF) bolts.

2019年11月7日 · I’ve been shooting .380 in my M11/9 for 30 years and purchased the CF-W 9mmA bolt from Vegas SMG to try in both the .380 and 9mm uppers. I bought a .380 slow-fire kit in the late 80’s because of the high rate of fire of the 9mm, also I already re-loaded for the .380.

2018年9月2日 · I just read over the SWD ad again. The "Hi-Low" kit included two M11/9 uppers with 9mm and 380 bolts/barrels. SWD claimed it reduced the ROF to 700 rpm with 380 ammo. The 380 bolt was 9mm length with the older style 380 extractor. The kit cost $350.00 in 1984. Medphys said it worked with the M11/9 9mm bolt and 380 barrel.

2006年10月19日 · The micro uzi smg, which was originally a closed bolt gun, or the MAC 11 .380 open bolt? I dont just mean the obvious stuff like that the micro will have better accuracy, but I mean in terms of durability to normal wear and to the environment, and the quality of construction, as well as just customer reviews basically.

2019年3月22日 · I use an Octane 9 on my M11/380. I have several uppers. 1- with a ILWT 3 lug barrel and 3 lug adapter 1- with a short 380 barrel threaded 1/2 x28 1- with a M11/9 9mm barrel with 1/2 x28 adapter 1- with a OEM 380 barrel that I had a …

2025年2月6日 · The early 11/9 carbine upper receiver was built using leftover RPB M11 .380 carbine barrels and shrouds rechambered in 9mm (probably the rarest one of the batch). Just felt like showing off the set! Now if I can only find one of the M11 .380 uppers that has holes instead of slots like the M10 on the top.

2015年11月16日 · Any full auto rated 9MM can will work on the full auto 380 guns too. Stay away from the OEM M11/A1 mount. Think new barrel, 1/2 X 28 or 3 lug. While 380 is subsonic and pretty quiet you get more blowback from the ejection port then with 9MM so you may want to buy a gas kicker too. I hope you are getting a good deal on the gun Dude.

2018年3月22日 · I am interested in the idea of a M11A1 which would originally be .380 of course but turned into a dedicated 9mm with a tungsten CF bolt. I believe I would need one with a magwell that would accept Zmags. Any other advice as far as models and such. Sams at practical could most likely switch out mag wells so not a deal breaker.
