AR build issues

[AK0perator47]

Great information everyone! The more I worked it by dry fire the better.

i didn't read all the posts so this might have been mentioned but my friend had this problem and I fixed it for him, he installed the small disconnector spring in his trigger pack upside down, i assessed the problem and switched it and it ran 100%

Dry firing is not going to a problem go away. Have you taken the FCG out and confirmed correct installation and no damage to the springs?

Are you certain that the hole in the gas block is aligned with the gas port on the barrel? Failure to function is likely a gas issue. Failing that, I would try a different magazine.

Multiple magazines have been tried. All work perfectly fine in other rifles. The upper is from a different rifle that has zero issues.

I am going to triple check again the disconnector spring. All of it is installed correctly but just because I checked maybe I missed something. Doubt it but it is worth checking.

Snug. I am willing to bet that it's the disconnector of the LPK. One of the guys here is sending me one.

Thanks @bolus

Went out in the mail today

Sweet... well I took the fcg apart to verify if disconnector spring was installed upside down and it's installed correctly after I had to track it down. Stupid thing came out and I dropped it!

 

[andersencs]

The disconnecter spring is critical. Broad base should be down.

Replaced the FCG with the one that @bolus sent. Have to see what happens when I go shooting. Btw, the disconnector spring is face down/ large size is down. Nothing looks out of the ordinary either. These are pictures of the FCG that was in the lower.

Many kudos to Bolus for helping a brother out !
Hope that thing just runs when you light it up.

Don't forget to oil it.

I have three Anderson lowers on the way to my FFL. Delivery ETA is Friday. $101 shipped.

Are Anderson Lowers a good value? I am thinking about about buying a few lowers and try doing my own build.

AR snobs would say no. Funny how Anderson, Aero, Spikes and a few others are all the same lower with different stamping.

I have 3 builds on Anderson lowers. They shoot just fine. And anyone that tells you the quality of the lower will affect accuracy has probably drank straight from the toilet.

Oh, and once you roll your own, you will likely NEVER buy a factory AR again.

I have just came back from the range. My AR build is able to fire the first round and it picks up the second round but, the trigger is dead. I am curious to know what is going on.


The lower is a Spikes Tactical with a Maxim Defense CQB stock. The upper is my Bushmaster 16" barrel.

I am not sure if it's the buffer or the trigger. Here is a video that may help. Anything else that would help you help me just ask.

You are undergassed. Use a lighter buffer and lube.
I have built a few, and adjustable gas blocks or lighter weight buffers will solve your cycling issue.

There is no cycling problem, the weapon fired, the BCG extracted & ejected the spent round and stripped a new round from the magazine into the barrel extension, just like it suppose to. The issue is an out of spec FCG or lower receiver.

Yeah but sometimes their so cheap I can't help myself.

Yeah, these days they're practically giving them away.

I'd rather pay double and buy a 80%
