 Problems with SIG 522

Been having a few problems with my new SIG 522, thought I would share! Took it out for the first test shoot, put 250 rounds down with only one FTF. I blame that on the fed bulk .22lr from wally world. I then had a nice trip to black dog machine! After a short visit, and partial tour meeting the fine folks that build the mags, I left with my 50rnd drum and a bunch of extra goodies!! Thanks Black dog, you guy's rock!! Someone told me BDM mags suck on some setups, so I high tailed it to the range! Another 240 rnds with ZERO malfunctions! I think to myself, this is the worlds best .22 Rifle! Get home and strip for cleaning, when I notice the front site base is loose. WTF? I work my way down and find the barrel nut has worked it's way loose! Double WTF!! I jerry rigged a tool that would help re torque the barrel/barrel nut (Pretty sure a CAR spanner wrench would have done the job) and went to work fixing the 522 up with some locktite!! Take her out to the range for a test shoot. Get 400 trouble free rounds down range when all the sudden I hear a "SPROING"!! You guessed it, the dreaded E clip problem. Cleared the rifle and broke it open to find the rear e clip failed. I finally found 1/8th e clips at home depot for .38 cents per pack of two. MY local NAPA auto parts store didn't have them, and wanted .89 cents each if ordered! Pass!! I just got everything right again, when I noticed the rear sling attachment was missing. Must have worked it's way loose and went AWOL at the range!! Not wanting to have to send the rifle back for a freaking screw, looks like I will have to pay for the new one! Thanks SIG! I appreciate your lack of engineering, and want of locktite!! The good news is, I still like this rifle!! Barring any more malfunctions it is a really nice shooter!

Side note: Never load the BDM drum unless your ready to shoot! I loaded mine, then tried to unload it and the thing jammed up so bad I had to take it apart to clear it! With two pages of instructions on how to dis assemble it, that was no easy feat! If you buy one, take it apart and back together again a few times to familiarize yourself in doing it right! No malfunctions so far, works like magic every time!! And BDM does make the SIG mags in case you were wondering

Can you explain this part a little more clearly please? How are you unloading it in a way that would be different from the magazine feeding into the rifle? Have you tried it for reliability purposes yet?

I doubled the forward e-clip on mine and have had no issues since. The forward clip is the one that let loose on mine, so that's where I doubled up. I'm not sure if the slot for the rear clip will allow them to be doubled.

Well lets see if I can clarify things a bit. The drum has a thumb activated tensioner in the back. To load the rounds you pull tension off with your thumb, then feed a round repeat X50!! To unload the drum you do the same thing! Release some tension and remove a round X50! I have unloaded magazines thousands of times. But the two times I tried it with the BDM drum, it jammed up inside the tower! The tower is the part that goes into the rifle. Like I said above, field stripping the drum is very close to rocket science Complicated!! Now I am not knocking the BDM drum!! I like it very much!! It has worked perfectly for me, with no malfunctions so far with over 800 rounds through it! Only problems I have had are with the cheap fed bulk ammo. With practice rebuilding the BDM drum gets easier. The regular 26rnd SIG and BDM mags have no adjustable tension. It is what it is!! And gets rather stiff at the 18 rnd mark!! The 25rnd mag loader I got from BDM works, but not very well! If they would widen the contact point by the width of the inside of the mag, it would be perfect!! I took the rifle out today, and put 400 rnds down without a problem!! I did double the E clips on the front, but the rear recess will only accommodate one!! Lets hope it all holds together. I really do like this rifle!! And the BDM mags all work flawlessly!!

Another side note: I now have 8 E clips in the PG just in case!! I am working on adding some critical parts from SIG to this little emergency package, just in case!!
