Is this normal? Stripped lower.

[Brianma65]

I recently purchased this for a build but decided to go with a complete. I sold it yesterday to fellow member. Upon closer inspection I noticed , what appeared to be less matarial on one side, where the buffer tube screws in . So before I take his money , I need to know if this is the way it's supposed to be. I looked this thing over several times and only noticed this last night.View attachment 64999View attachment 65000

NEA lower?

I am guessing SFRC lower, and mine looks the same.

 

[Brianma65]

Yes SFRC, so this is not the same as all other lowers?

It is the clearance for the forward assist which is quite normal in some brands of lowers.

OK thanks, I didn't want to sell it to someone , if it was messed up.

How is a counterbore in the threads for the buffer tube related to clearance for the forward assist?

 

[Brianma65]

Well , I sent a couple pics to the buyer. I'll let him decide, before I take his EMT.

Mine looks the same as yours. Makes sense about the clearance for the FA. I texted you a photo of my lower.

Cheers,

Please explain how a counterbore in the rear of the threads that accept the buffer tube provide clearance for the forward assist.

If it was, just take a moment and imagine how different this thread would be.

Who makes SFRC lowers?

Who makes SFRC lowers?

NEA , I think. But is it common with all lowers to have matarial missing from one side? If so then it don't matter who made it.
It just looks so odd,as if it wasn't done on purpose.

Well then this thread may not turn out so different after all.

 

[OkayShooter]

Hmm odd considering my Norc CQA has the same amount of material on each side of the buffer tube, and its got a forward assist.

I'm calling malarkey on the "clearance" for the FA.

 

[Brianma65]

LOL, before this thread goes crazy, could someone post a pic of different stripped lower? Thanks.
I don't want to sell an out of spec lower , is all.

NEA didn't make our lowers. It was made that way on purpose.

I would strip mine, but its a PITA to install the Magpul M93 stock.

Even in blue prints, its even on each side.

Its not counter bored as much as more material is removed for clearance. A number of brands do this.

 

[Brianma65]

OK then, thanks for the help. Appears it's done on purpose, so now I feel better selling it.
