What are some of the issues you have had? I have not experienced anything wrong with mine yet, but I also have not had it very long either.
Without writing a page of known defects let me just say since you have not owned it very long.....
The first problem you will have (my guess) in the first 3000 rounds there will be the screws in the BCG coming loose and becoming jammed in the BCG causing either scoring or a total jam requiring you to dismantle the group and replace the sorry cheap aluminum screws and loctite them. There are even youtube videos showing this problem and thusly a brisk business on replacement screws for sale.
The ejector is trapped along the side of the BCG housing and is held in place by pressure and 3 little plastic nipples. As the rifle is shot the housing tends to become loose with the screws furnished to hold the assembly together. The ejector then will shear the nipples and again jam or make the gun inoperable. Fix is to rivet the ejector to the BCG half.
Do not leave the GSG-5 mags, which are problematic to begin with, loaded....I have 7 mags but due to research and horror stories about weak springs in the mags I have not even tried leaving rounds in a mag. Yes not supposed to mess up a mag being loaded; all I can say is see for yourself and maybe you will have better luck than those who complain about the mags.
The GSG-5 IMO is one of the worse out of the box .22 rifles I have ever owned.
Now before someone gets their feelings hurt....
Once you replace the stupid cheap aluminum screws add loctite to new screws/nuts and periodically dismantle the halves of the BCG to check for anything coming apart (just wait they will) it is a fun little rifle to shoot and women and kids love the rifle for it's weight and cool factor.
Oh did I mention the take down screws and how the original stock out of the box wobbles.....
The GSG-5 is over $300 and the mags can be as high as $27 each which is stupid expensive for what you get. AR .22 mags can be had for $17 and that ain't all that good but you can leave them loaded; the ones I have you can.
IMO GSG-5 was an Airsoft that they tried to make into a .22 rifle on the cheap.
Did I mention the after market charging handle buffer or the cheap hard to find screw that attaches the handle to the tube? Oh and all the feed ramp and chamber cracking; not many but enough to get people's attention.?
One of the guys here at THR lubed his BCG and it removed the cheap sorry paint that was used on the BCG halves.....Do a search here at THR an maybe you can find it..Have not had that happen with mine but I did polish/remove the thin no stick paint on the half the ejector fastens to.
The GSG .22 1911 is a much better product to include real mags. But I almost did not buy one because of the engineering I saw on the GSG-5. Jury is still out but so far it appears they got it much better with the GSG 1911.
Again these are widely known problems; with a couple of days, not hours work on the GSG-5 it can be made into a more reliable platform and is fun to shoot....But out of the Box it could have been much better for about $1s worth of proper screws, fasteners, and 2 rivets..Just my opinion, sorry.
I still own the GSG-5 and after a lot of work it seems to function better than it did when new for sure......but it is the only firearm I have ever owned I honestly thought about beating a tree or telephone pole to death with it. My luck some cheap plastic piece would come off and hit me in the head or eyeball during the destruction process!
Hope you have better luck than many who owned one before.
