You can try contacting GunTec via phone or email at this link: https://guntecusa.com/contact/ but in my experience it's easier to go to your local ACE hardware with the part and check out their screw section. Bring the part in and match it up. Most ACE Hardware stores have a special section with gun screws. In the past I've bought both cup and knurled set screws there. I've used them countless times to not only replace screws but upgrade them in strength and length as well.
Please email us at techsales@opticsplanet.com regarding your question with the Guntec USA AR-15 Reverse Thread Slip Over Socom Style Fake Suppressor.
Yes. The Guntec USA AR-15 Reverse Thread Slip Over Socom Style Fake Suppressor includes the adapter which gets screwed to your threads, then slide the shroud over your barrel, and lock with set screws.
The Socom fake suppressor screws are not a standard size. They are proprietary. If you get us the customer’s address we will send him a set for no cost.
The 7.62x39/9MM model has a 1/2x36 thread pitch. If you need 5/8x24, then you want the 308 model.
You need about 6.5" of barrel to properly use this.
No, this will not fit that barrel since it has an OD of .875". This slip over requires about .750" or less of an OD.
Yes, this is for a 1/2x28 thread pitch.
If you can remove your current muzzle device, yes, it will fit.
Yes, as long as your handguard is large enough in diameter, you can mount this under it. The holes are just for show, they do not vent any gasses.
