IF you are haveing trouble with your Ar Pistol. Just ask me. I have built enough of them. To help you out.
If you are using M1S Pistol kits. You might get one that might not cicle. If you are using the 1911 kit.(16 pound spring) Try using a softer spring. Are a lower grain bullet....
IF you are using a a car stly tub. You can try cutting the spring down two are three rings.... But I have cut 6 off one. The buffer spring was one of the silver, and stiff spring. That I had left over from another build...
One of the best pistol kit I have every built. Came From Model 1 Sales.....I have used almost everyones kits. And I keep going back to Model 1 Sales.
Now for the lowers.

If you are building your own. You might want to try out The JP spring kit. And JP @ stag Triger Group..
I get most of my parts from Model 1 Sales, are Lone Star Whole Sale..
I use Texas Star Group for barrels, and stripped uppers.
Because they always have the parts that I need.
If they do not have the parts they get them very fast......
For me...
The best Gun Oil I have every used...
Is Rem Oil with Teflon. All you have to do before you put it together. Is to spray it two are three times. And let it sep in. Do not whip it off. Just let it sep in. The Rem Oil will penatrat the coating and make a layer of Teflon...
You will realize that the parts go right in. And the coating on the parts are kind of hard to scratch..
