I have two , O.A. AR's I built from there Parts ( matched upper & lower)and many more I built for customers , including some select fire M16's(lowers rec. were not O.A )and all were built with S/S heavy bbl's.( who needs chrome lined ). The only problem I have had and it was afterover twenty years , is a trigger sear partly sheared off on one of mine own and caused it to double tap once in a while. Mil. spec. triggers are really hard to work with to get a good trigger sear engagement , by working them you take off too much material and that reduces there workable life ( twenty years is pretty good ).
The new systems (match triggers ) were not available back then, like a lot of the upgrades available today.
Be careful, according to the BATF you have a machine gun and could be prosecuted.According to arecent ruling ANY gun that malfunctions andcooks off a few is now a machine gun, including a double barrel shotgun thatmalfunctions and fires both barrels.

If you don't feel like reading 34 pages... He loaned a gun out to friend and it malfunctioned at the rangewhere some cops just happened to see it and the friend got arrested. Guy hears about it goes down to the police station to clear it up and gets told he's being charged too. BATFtakes the gunto "inspect" it and can't get it tofire in "full auto" again. It's tested again with soft primered ammunition and 50% of the time they get it to MALFUNCTION (as in not timed fire but just cooking a fewrounds off then jamming). They go tocourt and the BATF refuses to provideevidence that proves the mans innocence(product recalls, open letters, another court case going on at the exact same time where the BATF isclaiming that the exact same model of rifle is not considered a machinegun)...even going to the point of lying to a federal judge. Guys appealing right now and is probably going to get off once allowed to enter that evidence.
Oh and it was an olympic arms AR that started it all
