The best protective cap for dolos sets!
These things are awesome and leaps and bounds above the orange protective sleeve made by dolos! I've got them on a pistol build with a Dolos quick change and they are a must. It's a polished and well set up rig with Aero M4E1 limited edition "pew" reciever set in FDE, gear head works tailhook, fostech binary trigger, all ancillary hardware is titanium nitride coated including BCG, 223 wylde barrels in 7.5" and 12.5", brigand carbon fiber weave handguards for every barrel, superlative arms gas blocks, and now an 8.3" triarc 300BO barrel set up. No expense has been spared and that's why I use these caps. They are obviously superior to the Dolos brand caps in securely locking the handguard from contacting the barrel and muzzle device which is a must when so much is invested in this rig. Just get them, you won't regret it.
