AR pistol help

[Northgagunman]

It's an Anderson build. Anderson lower and upper with 10.5 stoner barrel. Only fires one round and chambers the next. Light strike on second round. Any idea what the issue could be? Or if anyone local in the Cumming area is willing to take a look at it pm me please

 

[Mr. Booshie]

What ammo are you using?

 

[Northgagunman]

Federal 55g fmj brass, pmc bronze or America eagle xm193

Hammer spring installed correctly?

Is the trigger resetting all the way after the first round?

Yes Hammer spring is in correct.
No sure on the trigger resetting all the way. Any way to test this?

After market trigger? My ALG trigger came with 2 different springs, a 4.5 and 6 lb spring. It warned of light strikes with the 4.5 lb spring.

When I got from the guy it had a 4.5 lb trigger but I changed it to a jp spring

Sounds like that may be it

Sounds like that may be it

Even though I changed it already? Changed both trigger and hammer springs

You changed hammer springs and it's still happening? Or did it start when you changed it?
