Just reporting back that this was an easy fix. Finally got around to tearing the AR down this morning. Discovered there was no disco spring in the gun! Made one up from some spring stock, and good to go (at least dry firing okay.) Best, Jon

Thank you taliv. I have a technical book on the way, and I'll be diving into it when it gets here - figure these days, it can't hurt to know how to repair the rifle in the field if necessary. I deeply appreciate the help, you guys. Thanks so much. I'll let you know how things turn out...

Aha! More memory is starting to return. I now remember the REASON I changed the fire-control group. The rifle was double-tapping. That was years ago. With the rifle's history being one full of alterations, and with the upper and lower being from different manufacturers, I am getting the...

Hi, BBBBill. Glad to be here. Been a member here for quite awhile, but haven't posted much because my "hobbies" got so weapon-specific if you know whata mean. ;). I did replace the trigger group a long time ago, but I cannot remember whose parts I used. I am 100% certain that I used good...

Oh, and taliv is correct: no shroud.

The former. If one looks into the port when the rifle is locked up, he'll see the front edge of bolt right in the middle of the port. In other words, in the rear half of the port you see bolt, and in the forward half of the port you see air.

My AR is locking up during cycling when the bolt gets 1/2 of the way back to battery. In summary, if I hold the trigger rearward and cycle the bolt, the bolt stops on something 1/2 of theh way back to battery. It has to be some kind of mechanical interference among parts because it occures...

My old ADD brain tends to do better with visual aids, so here are a couple of little graphics I did up awhile back to show the bare-bones basics of how the disconnector works - what it does, and how - and common errors folks make when prepping disconnectors. The graphics are obviously not...

Right you are, schmeky! I have a LARGE box of "scrap metal," but hey, that's just tuition, and it was darned well worth it for the pleasure learnng continues to provide. I have never had the chance to fool with a Norinco, but I've heard lots of folks say they love 'em and that they can be...

By CMC, do you mean Chip McCormick? Heck, I've never heard, or experienced, anything buy top quality from their parts. In fact, I probably use their fire-control parts more than any others. I have had some trouble reaching them in a timely manner or receiving adequate responses from them when...

Okay, now if you're going to do this, do not make the mistake of choosing parts on price alone. That can cause you headaches, and believe me, I have learned from the saying (wish I knew who originally said it), "Buy cheap, buy twice!" Instead of buying cheap, save your money and buy good...

Fitting - REALLY fitting - a trigger and a GS are things that you can certainly do yourself, and if you know what you will be doing before you cut, and then proceed slowly and carefully, there is no reason on earth why you can't do a jamb-up job on both counts. And that's where it's a great...

John, you are embarking on one of the most rewarding hobbies going. The keys are to be sure of what you are doing before you cut, and to proceed slowly. Building a drop-in parts gun is not hard, and frankly, building one of better quality is not that much harder, again if you make sure you...

You know what they say, John - with regard to me, at least, "Even a blind pig . . . " ;) Best, Jon

Just give them a call - they're great foflks - very responsive, and can answer your questions directly. Best, Jon
