Would a standard AR-15 retractable stock fit the 522/556 carbines?

Well, this afternoon I shot my GSG-5 for the first time after the trigger mod - and although it preformed well, I did not like what I saw. Heavy gun powder residue on all of the casings and on the chamber (ammo did not change). After 22 rounds, my chamber was jet black, and the casings were two tone black and brass. Prior to the mod, one of the things I noticed and impressed me the most was how clean the chamber would stay after running several magazines through it. Not sure what shortening the trigger pull did to make this happen. If this isn't happen to the rest of you, then it has to be because of my near zero slack. Tomorrow I'll try to adjust it so there is slightly more slack.

We had a shooting involving the .22LR in our jurisdiction just a few days ago. I can not get too specific because it is still an open case but here are some facts: 13 year old male took a single .22LR round from a six inch barrel pistol. Non contact range. The round entered the soft tissue just posterior of the chin. It continued through the nasal cavity into the cerebral cortex. The round stopped just short of exiting the top of the skull. Although there was not much blood loss, the victim was pronounced deceased within 5 minutes of the call. As soon as I hear the ammo type I will update the post.

Thank you for the detail explanation. I am done with my mod. Took me a little while since at first I left the screw out too far. A quick trip to Ace for the longer screw and I was done. The trigger slack is completely gone. I will test it out tomorrow. Picture one shows the OEM screw too far out. Picture two shows the longer screw from Ace with a nut serving as a spacer.

Killibreaux, Do you think this will put a little extra wear on the sear spring since it will have slight constant depression? I was thinking maybe a slightly stronger spring? Your thoughts...

Wow, I 've been missing out on this (busy messing with my M1 Carbine). Great mod! I am going to get right on it. My GSG-5 / HK94 has been shooting butter smooth since the hammer strut mod. Killibraeux, what about a longer screw with a spacer just to keep some torque in the area of the backed out screw?

Edgecrusher, this mod is not as difficult as all these back and forth post may make it seem. However, if you feel you are not up to it don't try it. The good part is, if you ever feel you want to give it a try, purchase a hammer, and a hammer strut from ATI customer service, and start dremeling. If you mess up, you can always put the original parts back. As for the feeding issues you stated, are they happening with different magazines as well? Have you tried the polishing of the chamber we've recommended?

You should not have a rattle. The magazine safety lever rested on a detention in the trigger plate only. Check your trigger assembly again. I wouldn't add anything in there that wasn't OEM. Compare it to the ones here. Notice there are no marks on this lever.

Nice work on the hammer SnakeWrangler. Here is a little treat for you guys... THE FOLLOWING IS A TACTICAL22.net EXCLUSIVE. Now I shall reveal my polishing method. I can not stress enough, the improvement of the action when certain parts are polished and buffed out This is for the experienced armorer. Do not attempt if you lack any armorer skills. The following tools and materials needed: Dremel tool dremel 414 polishing bits x2 (may use more) Ryobi white rouge buffing compound (H) 2-5 microns Flitz metal polish a cotton rag (i used old t-shirt) WARNING: All parts need to be removed prior to being polished. Polish parts AWAY from your other parts--compound will splatter! Wear safety goggles and keep mouth closed or wear a dust mask. Parts I polished: Hammer ( contact surfaces) Hammer Strut ( where the srtut contacts the hammer) Sear -contact points (you need a punch to remove the pin) Bottom of breech bolt (where the breech contacts the hammer for engagement. Use one buffing wheel for each compound. Start with ryobi and buff out with cotton rag. Make sure the part is free of any ryobi residue before applying the Flitz polish. Note: If you run the dremel at high speed 45 seconds should suffice. On low, over 1 minute. After the Flitz you will see the part you polished looks like jewelry, and is the smoothest thing your fingers have ever touch. Put your parts back together and take it out for a test.

The spring may be in but the bolt stop may not be seated properly. Pull your breech out and check the bolt stop to make sure it is properly seated on the breech block. What brand ammo are you using?

Shot another hundred flawless rapid fire rounds yesterday. It's amazing how clean my GSG stays with CCI Mini Mags. You could barley tell the guns' been fired. Polishing the feed ramp helped tremendously as well. :grin:

Is that with the magazine in or out? Take pics and submit as much as you can-we'll walk you through.

Well there is only one thing left to say; Sweeeeeet modification!!! i just took her out to the range today. Not only does the trigger feel smoother (all the polishing paid off) but the over all functioning and cycling of the action feels so much better as well. The casings were found around 17 to 20 feet from where I was shooting. Thanks to you Kilibreaux, all the time money and effort I put into my SEF lower has paid off! Can't wait to take her out again tomorrow!

I see what you meant by self extraction. If I pull the slide back fast (not nearly as fast as id the gun was actually cycling during fire) the round pops out of the chamber just from the speed of the retracting bolt. I didn't take a photo but I also re-shaped the grind of the hammer more to the angle of the sear. The trigger action feels sooo much smoother. I have 29 years of firearms experience but never got into modifications or armory until I acquired my GSG-5. Then again come to think of it, I never had to prior to the GSG-5. Thank you for all the help, you are a wealth of f knowledge. I can't wait to take her out to the range.
