As per a prevous post about SI's original Oppressor Concussion Reduction Device for some compatible muzzle devices the A2 Blast Shield is meant for any rifle using an A2 birdcage and it can be quickly installed or removed as needed.
On the range, the A2 Blast Shield does what it promises: it cuts down muzzle blast for the shooter and shooters on the same line of fire as you. A 5.56 AR-15 with an A2 birdcage hits about 165–170 dB at the shooter’s ear in open settings, and indoor ranges make it feel louder due to echo.
The A2 Blast Shield redirects blast forward, noticeably reducing the concussive effect on crowded firing lines, covered outdoor setups and to a limited extent, indoor ranges too. Testing showed it’s a courteous option for group shooting, easing the noise for those next to you as you can slap it on in an instant if more people join your firing line at the range.
