Description

The A2 blast shield provides concussion mitigation to A2 muzzle devices, and Griffin Armament SDQD flash comps, as well as Griffin SDQD muzzle devices which are A2 length (listed below). Compatible with the Minimalist brake shield thread protector, and also capable of converting the Optimus silencer to an 8.4" OAL 17.4 ounce, A2 mounted configuration.

The device and the collar are both compatible with the car stock wrench tool included with the Optimus silencer. Additionally a strap wrench (not included) may provide useful utility especially when removing accessory mount interfaces from the Optimus silencer.

Weighing 5.7 ounces, the Optimus A2 mount can be used on 5.56mm AR's to and with the 30SD flash comp it will support centerfire calibers up to .308 Winchester.

Mounting Instructions

The rear slip-coupler unscrews completely from the main body of the Blast shield. The coupler is slipped over the muzzle device at a 45 degree angle, then straightened (with the threads away from the barrel) to allow the coupler to slip
into the rear accessory/BFA ring of an A2 device. The tapered end of the main body of the Blast Shield is then inserted between the coupler and the muzzle device. The coupler is then re-threaded onto the main body of the Blast Shield while still in the accessory ring.

We do not study the myriad of devices on the market. If a company wants to see if their device is compatible they can send us a blueprint of the device and a sample. Email: Tech@griffinarmament.com

    A2 Blast Shield

    Published by Shawn on 1st May 2020

    The fit and finish on this mount is beyond what I expected, extremely precise machining. Installation is about as easy as it can be and provides a very solid mount for my Optimus.
    As others have mentioned it doesn't quite work with a 5/8x24 A2 flash break, so might want to consider another mount or picking up the 30SD as well.
    Over all I'm very happy with this mount and would not hesitate to purchase again.

    I like it

    Published by Seth on 4th Oct 2019

    I am a cheap and lazy person. Most of my hesitance about using my Optimus suppressor on my ARs is due to not wanting to buy a new muzzle break for each and install them. This blast shield installs easily and works well in conjunction with my suppressor.

    Love this A2 mount

    Published by William on 12th Apr 2019

    This attaches to most A2 Flash hiders. Easy and fast to move from AR to AR. Use with my Optimus silencer.

    Works great!

    Published by Mike on 27th Sep 2018

    This works awesome on my kel-tec RDB and cmmg guard 9mm. If they would send it with the Optimus to start off with instead of the taper mount I would have been happier. Oh well, this saved a bunch of money by thread adapters etc. A must have for any Optimus owners.

    Fucking Sick!

    Published by Mike Franklin on 31st Jul 2018

    This thing is bad ass. I bought an optimus thinking it would do almost anything. It does! But this thing was icing on the cake. I threw this on there and now its doing duty on my M&P AR. My buddies are jealous as fuck. Hell yeah merica!
