Free Float Hand Guard Thread

[ircrapid]

Hi

I have some one making up a custom hand guard

I havent removed the free float guard as yet but can anyone advise the thread holding the handguard in place.

Some forums state 1-7/16 - 16 TPI - 2A and others 1-7/16-18 TPI - 3A

 

Thanks

Ian

Armalite, or DPMS pattern?

Armalite is 1-7/16 x 18.

 

       *** Duh........didn't even pay attention that this was under the (dreaded) <laughs> RRA category. Not sure about the RRA receivers.

RRA uses the Armalite thread (18 TPI UNF) on the LAR-8

I was born/raised in Singapore before moving to the States. We had 4 mil or so then in 270+ sq miles (about 3x the size of DC), and zero guns available to civilians.

 

....but all males in the country have military training of some sort or other.

 

BTW, welcome to the forum!
