Got to the range today for the first time with my AP5. Over 300 rounds fired using both MKE and H&K mags. I started off with 124 grain NATO ball. Sights out of the box were perfect for ringing steel at 15-25 yards.
After a couple boxes of ball, I switched to reloads. 147 Zero FMJ, 4.0 WSF, loaded to 1.10. Recoil was much smoother. Gun continues to run 100%. After 150 rounds I can feel the front hand guard warming up. At this point I am convinced the gun is settling down after an easy break in. So I switch to my favorite 9mm load. Zero 147 JHP 4.0 WSF. It ran 100% Then I am feeling brave. I try some Precision Delta 124 jhp flat point version. Gun eats them like candy. Last ammo of the day. Federal 147 FP. The one and only failure to feed was one round of this factory ammo. Observations: Very pleased with my AP5. Recoil was noticeably less when shooting than AR15 in 9mm using the same ammo. I shoot left handed, the AP5 does not spit powder in my face. The AP5 slings brass way on out there. Atlantic Firearms has a new happy customer. The MKE mags are bargain priced and they run great. I need another AP5. This gun is fun to shoot. Future plans: I plan to install a rail for an Aimpoint and enjoy shooting suppressed. |

Sounds like a winner. Did the one malfunction you have happen to be the last round in the mag? I sometimes get ftf on the last round on MKE mags if it's anything other than round nose. As a result, all my mags full of subs or HPs have a ball as the last round.

I have both. I got the full size first, followed by the K. I shoot the K and carry it around more frequently, but am still Glad I have the full size. It's fun to dress it up in different "eras".

My Zenith K has horrible gas to the face when shooting suppressed left handed.
I haven't tried my AP5 full size with my suppressor (Gemtech Lunar 9) yet. |

I've seen some say their SP5 is heavy grain and or flat nose Sensitive. It a good feeling when your AP5 eats everything!

Another trip to range today. 200 rounds of 124 fmj reloads. 124 zero fmj, 5.0 WSF, 1.15. 50 rounds of factory 115 fmj.
100% function. Starting to learn the feel of the trigger. Looking forward to a detail cleaning to further get to know this jewel. MKE mags are working so well I ordered a few more. |

My AP5 has been extremely reliable. The only failures to date with a variety of bullet weights and types have been last round failures with the MKE magazines with non ball rounds. The HK mags have been flawless.
It’s about 2 MOA accurate with 115 gr XTPs at 100 yards using a Burris Fast Fire III. It’s also been 100% reliable with 147 gr loads and my Omega K suppressor.

I only had it happen one time. It was a MKE Magazine with the last round of HST 150gr in the AP5-P. I wonder what the difference between the followers and or spring are? |

I don't think MP5 triggers improve much with use, like AR and Glock triggers. They start out bad and stay there. Some polishing can smooth it up some. Good grease in the right spots. |

I don't think MP5 triggers improve much with use, like AR and Glock triggers. They start out bad and stay there. Some polishing can smooth it up some. Good grease in the right spots. The problem with MKE triggers is that they leave that neutered auto-sear in there .... combine that with the mods they make to the hammer and it results in mushy resets, and heavy trigger pulls. I beveled/contured the surface of it that rides against the hammer and now have a nice, crisp reset, and a lighter pull. I'm going on 8K + rounds on my 2015 Zenith imported MKE full sized gun, and haven't replaced a single part ....not an extractor spring, not an ejector .....nothing. I have never replaced a single part in the HK-94 I've owned since the mid '90's either Every FTF or FTE was due to a single HK straight mag from the 70's ..... so I sold it to some clown who just wanted to use it to post pictures on Reddit. |

Interesting. Are there any write ups or tutorials about this MKE specific mod? Can the neutered auto sear be removed entirely? Once MKE grinds the auto sear notch off the hammer, the geometry of the "neutered" auto sear (trip lever removed and mounting points blocked) changes dramatically ..... it almost acts like a brake pad on the hammer ..... take an MKE semi pack, and compare its operation to an FA MP5 pack ..... it'll become quite obvious. The easiest option for most would be to just use a pre-89 HK semi pack. Taking a stone and putting the teeniest amount of radius on the surface of the bolt carrier that contacts the hammer will significantly decrease the effort required to charge the gun / retract the bolt as well. |

I'm not @DakotaFAL but I have 29 inch long Bulldog Ultra Compact Discreet Carry Case that perfectly fits my AP5 with brace extended. Mine is blue but Bulldog currently only offers black on their website: https://bulldogcases.com/products/ultra-compact-ar15-discreet-sporting-rifle-case?variant=46750485053721 The blue one is available on ebay. https://www.ebay.com/itm/164887055812 Mine also fits a 10.5 barrel AR15 pistol with brace and my Galil with 16" barrel and stock folded. I can cram in a 6 mag AR bandolier with each gun. |

Wish I was on the same boat. RMAed my first one before even shooting it due to off center bore, and the next two replacements were each worse than the last one. I've had enough and am trying to just get a refund now.

Finally shot my AP5 with some proper subsonic ammunition today- Fiocchi 158gr fmj
Had blown my fun money budget on the silencer (with an awesome 8 day approval time), and had to wait weeks for the ammo....  Attached FileNo malfs, other than the expected last round in the magazine malf. Very quiet. Neighbors were none the wiser. Ordered an OD green tropical wide forend for it today, a 100 degree locking piece, and a full case of the Fiocchi. |
