Guntec usa muzzle comp and blast shield - Guntec USA AR-15 Muzzle Comp w/QD Blast Shield

Not truly a QD, the blast shield threads onto the comp. I've owned this for 4 years now. Was looking back at old purchases and decided to review. First and foremost, she's thiccc. The weight is definitely noticeable, especially on a 16" barrel. I've had this on the wife's 12.5, and it was much more comfortable. However, it works extremely well on every setup I've tried it with. I've also threaded this on a 9mm pcc and was tolerable with no ear protection, though not recommended. It moves some of the audible "crack" of the round forward, but most importantly, the blast. It is perfectly comfortable to stand next to when someone is using it.
