  1. This gun will not properly eject spent rounds. It only jams…. Company does not return calls.

  2. If Escel Arms had a zero rating it would be too high. Returned gun to factory and they sent it back to me stating there was nothing wrong. They said I need to use CCI TNT 17 grain. That does not fix the problem either. The gun still bulges at case head and won’t eject spent rounds properly. It only jams. Company does NOT return calls at all. They will not answer the phone. You are given options of the automatic answering for the phone but not one is ever available. I would appreciate a response to this email. You have a lifetime warranty that is apparently not honored by you at all.

  3. These people are the lowest . My .17 blew up on me twice. they won’t respond to me except to take the gun back to fix it. I even offered to trade out for the .17 ruger they sell and no answer. They told me the same bs about the ammo. This weapon is dangerous. It cut my finger; chipped my glasses and scratched my friends face when it blew. They won’t talk to me now; they have the gunandall I have is a empty wallet. They need a class action put on them. Mayby MICHROTECH SMALL ARMS RESEARCH COULD HELP THEM OUT?Something needs to be done.

  5. Excel MP-5.7 Review
    All, this is my first post here, and I would like to recount for you my success with a fine Excel Arms product, the MP-5.7. I would like to do this….I would also like to have hair, but that isn’t happening either. Let me jump right into it.
    I returned from Afghanistan in early 2014, and decided I wanted to purchase a 5.7 chambered pistol. The Excel looked like a bargain, and the longer bull barrel promised an increased velocity. I shopped gunbroker, and eventually struck a deal in November for just under $600.00, including the FFL transfer and shipping.
    The pistol arrived shortly after, and in December, I went to the range with my new acquisition to take the measure of the pistol. This was somewhat curtailed by the minor fact that the pistol DID NOT FIRE. Not only did this new, out of the box pistol not fire, it did not even show a primer strike in several dozen attempts. I have purchased 110 year old Colts, new pistols from Kel-Tec to Sig and have never, ever, had a turd out of the box, but I surely had one now.
    I went on to the Excel website, and contacted them immediately…..nothing. I waited a month, and repeated the procedure…nothing. I called, and was trapped in the hell of endless phone message, so I wrote again, and on 21 May 2015, I received the following response:
    “Hello – Sorry to hear about your trouble.
    Can you check to be sure the screws, specifically the rear screw on the top of the pistol rib is snug down tight with the allen Hex wrench.
    The screws can become loose and this will cause malfunctions. They need to be kept snug down tight.
    If after you have checked the screws, then you can send the firearm into us to check out for you.
    Your Return Authorization number is RA# XXXXX.
    Ship it to our address listed below. Do not include any live rounds, but do include your magazines.
    Please fill out the warranty card and send it in to activate the warranty.
    While not exactly pleased with being told to repair my own firearm before sending it in, I tried it, no joy. I shipped the pistol to Excel Arms, which Fed Ex (on my dime) confirmed arrived on 29 May 2015.
    Insert long pause of hearing nothing here, not even an email confirming receipt.
    I wrote an email to Kathy on 01 June (no response) and a second on 10 July 2015, which stated the following:
    “Second Inquiry (first un-responded) as to the status of my pistol. I am becoming….concerned.”
    On 12 July 2015, I received the following reply”
    The firearm is here. I will get back to you on Monday or Tuesday to advise.
    Since then (it is now the early hours of 18 July 2015) I have not heard a word, through any of the vast communications options available. I have no pistol, no $600.00 and even if I received the item back tomorrow, it would be forever stained in my mind by indifferent and slipshod construction, followed by perversely bad customer service. This is a firearm, a somewhat serious product, and this bunch seems to care about neither their customers nor their reputation.
    So I am posting here, and to every related discussion board I can find. Please consider my experience with the Excel Arms MP-5.7 before you purchase this shiny doorstop. The typical negative customer service experience gets related between 11 and 20 times, I am going to try to better this number, and perhaps in doing so can create pressure on Excel Arms to better their customer focus.

  6. I have the Accelerator pistol in 17 HMR and .22 magnum barrels. The pistol functions perfectly with either barrel shooting .17 HMR or .22 magnums.
    Also have the rifle in .17 HMR and it too functions perfectly.
    Great guns!

  7. Well is it a great gun or a POS ? I really want a .17 auto but I don’t respond well to getting screwed. Did the guy WT Sane ever get his weapon fixed? Was the wonderful post from Jon a plant post from Excel Arms? I would really like to have some verifiable input.

    No, I am not associated with Excel Arms nor any other firearm mfg. company nor anyone in the firearm industry in any manner.
    I am pleased with my purchases of Excel Arms and just purchased another MP-22 Accelerator Pistol with the .17 HMR barrel included from a firearm auction website. I have not received it yet but am anxiously waiting to pick it up in a few weeks from the selling dealer over 100 miles away. I am confident it will preform perfectly as my other have.

  9. I have received and fired the above Excel Arms MP-22 with the .22 magnum barrel and the .17HMR barrel. this firearm, like the first one purchased – feeds, fires and ejects cartridges perfectly and is a fun shooter.
    Now with two pistols, each with the .22 Mag and .17 HMR barrels and the Excel Arms rifle in .17 HMR – all function as designed = perfectly.
    I am super pleased in all aspects. Also contacted Excel Arms with some questions which were prompted responded to and did purchase extra magazines which were received in only a few days. The customer service is excellent!
