I haven't posted in this thread since Eman930 and I had our initial problems with the malfunctions using the factory KAC SR15 rifles and our AAC 762SDN6 suppressors. Eman930 has fixed his problems; HOWEVER, I can't seem to get my rifle up to speed. Using the advice of other members, I have installed the Vltor A5 system and a Springco "green" rifle spring. Here's goes my frustrating effort to fix this over-gassed issue:
Please keep in mind all ammo used during this test was Federal XM193.
Step 1:
I installed the Vltor A5 System and used the stock weight buffer and Springco spring. I went to the range....fired approximately 35 rounds....and cursed uncontrollably as I had three malfunctions...all stovepipes. I can say that the A5 system caused the ejection angle of the brass to be more consistant at approximately 2:30.
Step 2:
In an attempt to increase the buffer weight to get the rifle to cycle properly, I added one additional tungsten weight and removed one steel weight. I (again) went to the range...fired approximately 35 rounds...and cursed uncontrollably as I had multiple malfunctions.
Step 3: (Today's Range Trip)
I added an additional tungsten buffer weight....now all the weights in the buffer are tungsten. I (again) went to the range...fired approximately 35 rounds...and cursed uncontrollably as I had multiple malfunctions.
At this point, I am at my wits end with this KAC SR15! When Eman930 originally posted this thread, we were contacted by KAC, who promised new ejectors and springs. THESE NEVER CAME!! After multiple attempts at trying to get this person to send the parts....we gave up and tried to fix things on our own with the A5 system.
My opinion is that I must have a barrel with a gas hole the size of a sewer pipe! I assume in KAC's attempt to satisfy the general public with their rifle's ability to cycle junk ammo, they have obviously ignored more of the higher-end user, which I was under the impression that the company catered to when I purchased my KAC products.
I am beyond pissed at this point and am considering parting with all my KAC rifles because their products don't do what they claim. When I pay such a premium for products....I except them to work flawlessly without exception.
Well guys....can you think of anything for me to try??? I'm all out of options...at least that I can think of. I would appreciate any help/comments that you can provide.
