OSS BPR2 Airsoft Mock Suppressor Unit by Madbull - Black

Operators Suppressor Systems (OSS) is an industry innovator with their Back Pressure Regulator (BPR). Unlike traditional suppressors the real steel BPR limits negative effects of pressure to the piston / bolt system and in essence creates a more controllable, more reliable platform.

The Airsoft equivalent of the BPR2 by Madbull gives a unique, extremely aggressive look to your rifle. If you're tired of the "typical" mock suppressor / barrel extension, slap one of these bad boys onto your gun. You can be sure your rifle will be turning some heads. The Madbull OSS is constructed from CNC milled aluminum that has been coated with a matte black finish. Authentic OSS trademarks have been stamped into the body of the barrel extension giving it a truly realistic look.

"This is a super solid mock suppressor with a great finish as you'd expect from madbull. It covers up about 3 inches of your outer barrel, so it's great for giving your 14.5 carbines or longer guns a suppressed look without a huge amount of extra length.

However, the biggest downside to this thing, is it's weight. It's almost 2 pounds. Not the hugest of issues, but with the recessed threads this has the makings of a great suppressor for a long barreled gun if it was lighter.

That leads to another point that I'm sure many people will overlook- how secure is your outer barrel? My vfc xcr is fine with this brick hanging off hanging off the muzzle, but a rifle that suffers from barrel wobble to begin with will definitely be a no go for this suppressor. Some good examples are the Sig mcx if you have a barrel extension and g&g 416 if they still make them with their old front wired barrels.

"Totally Operator!!
Runs on my limited edition H&K 417 350C kills some of the outer barrel landscape. Stands out from all the other suppressors in my unit that's why Special Forces rule, you get the best gear. Just know that this mock suppressor is a beast and you will not feel anything but pride with this thing running out in front of you (and a good forearm workout, got a magpul angled grip to help control the added weight). Totally sets your platform apart from all the other operators running standard tube versions.
