Awesome! Are you going to run a suppressor on it?

Awesome! Are you going to run a suppressor on it?

That's the plan. We'll see what the muzzle thread is of the Para barrel I ordered. The GB seller doesn't know the barrel thread spec or if the existing muzzle device is welded on. I may just suppress the longer barrel which is 1/2x28.

I'll test fire the gun later this week to see if it runs correctly. You never know with builds by other SOTs!

I plan to use the SLX-MG 6.8 can from the Sig Spear that a CA customer allowed us to keep. It uses a Sig QD flash hider that is 5/8x24, so I ordered a CNC Warrior adapter to mount it on 1/2x28 thinking that the Para barrel would have the same threads as the 18" barrel currently in the gun. I also ordered a .223 alignment rod from Accuracy Solutions to check concentricity. We'll see how it all comes together. The Para barrel is arriving today..

I received the barrel and it is the FN military 13.78" part with muzzle device that is not perm attached. It's likely that the thread is 9/16x24 LH.

This is the same barrel for double the price of what I paid on GunBroker:

I ordered this adapter to install the Sig muzzle device and suppressor:

Not sure there will be adequate clearance between the gas block and the can, but for $19.95 for the adapter, worth a try.

Quick photo with the Para barrel installed. No pivots points for the heat shield since the Para gas block has a short retention pin, but really, who needs a heat shield anyway. :


.
The only issues with the gun as received are a gas cylinder that won't come out. Likely installed incorrectly and beaten into place deforming the retention spring. Additionally, the lower back plate retaining pin is too tight for the receiver retaining clip and back plate retaining clip to function. The pin has to be hammered in and out. Whoever finished up the receiver didn't fit the pistol grip assembly to the lower part of the receiver perfectly causing this snugness. Both projects for another day since they won't affect function.

We can do that sometime. I'll test fire it tomorrow to see if it even runs right.

With the auto sear too?

The gun is a post 86 dealer sample, so built as full auto.
