MP5, MP5SD Owners and Gunsmilths-
I AM LOOKING FOR COMPARISSONS- if you own an MP5 or MP5SD, I'd love to hear your feedback as to what is "normal", similar/different or wrong compared to my weapon. I've had in my possession since January of 2012, the MP5SD built by TPM Outfitters in Carrolton, TX with an Urbach suppressor. Since then I've been to the range a couple times, cleaned it a couple times and have gotten familiar with the workings of it. Now, it seems that the Gremlins are starting to show and I am looking for someone who can repair and refinish my weapon so that it is correct and safe. I cannot afford a %1000 grade repair but I will have it fixed the Hk way... No Compromise.
1. Mine will only cycle and function correctly with Winchester NATO 124 grain ammo. I am using a 120degree German locking piece marked "MP 5 Action 1 MP 5 SD", German Bolt head IV date, and German carrier IF date(pic included). (and I'm assuming that the recoil spring is a regular spring and not from the "F" models.) All of these parts came on the weapon from the builder- I have not changed anything but the stock and if your thinking "it could be the rubber buffer", well that's why I have shot it with both the A2 and A3 stocks with the same results. The rest of the ammo I have tried will fail to eject between 1 and 5 rounds shot. I have tried numerous brands of varying quality and weights including Remington UMC bulk pack (had to try it once), Remington (green/white box), Winchester (not WWB), PMC, American Eagle, Sellor & Bellot and recently Hornady Zombie 9mm 115gr. I've shot 115gr and 124gr when I can find it. I have not tried anything marked +P though I am of the understanding that the Winchester NATO 124gr that DOES work is considered "hotter than normal". Is this normal or should it function on a wide variety of ammo?
2. I have cleaned my weapon thoroughly after each range session with either Safariland Break Free brand CLP, Remington brand Rem Oil and/or good old fashioned Hoppes 9 and have changed the butt stock back and forth no more than 10 times- (but lets just say that I did it 50-50 on/50 off) between the A2 and A3 stocks and have already worn through the finish and can see metal(pic included). Is this normal from removal and reattachment?
3. Now along those lines, I recently had a company called "The Gun Cleaners" in Waco, TX clean it in their ultrasonic tank. The representative assured me that they only use environmentally friendly cleaners that "are basically Dawn dish soaps but without the salts." Well, after two runs through the process (they were trying to get the carbon off the barrel which I DO have the expensive brush specifically for that task), my finish is starting to come up. My weapon is now speckled and this was obviously a bad finish to begin with(pic included). Any suggestions on someone to refinish it? I have heard mentioned Arizona Response Systems (which I like because he's an authorized refinishing center for Heckler and Koch, USA, for over 13 years), Investment Grade Firearms (which is a vender of HKPRO.COM, woot!) or "Ghilliebear" at Parabellum Combat Systems (also a HKPRO.COM vender woot!)
4. Along with the refinish, I'm wondering about some of the welds and "workmanship". Most of mine are good looking but the one on the front of the magwell (pic included) is a bit blobish and where the cocking tube is welded, I just wonder if that can be cleaned up a bit? (pic included). I'm also wondering about the piece inside the cage, should it hang down like it does?(pic included)
ANY thoughts ideas or suggestions? I'd really like to have a great shooter and a respectable looking weapon.
