Threads vs. lugs for muonting suppressors?

I'd like to get one of my AR15 uppers suppressed. I can have it threaded after AWB sunsets. Do better options exist for secure mounting and quick removal of the suppressor?

Oleg, several companies offer a Quick Detach that does what I think you're looking for. one part threads onto he muzzle and is left on permanently, while the other (the suppressor) is a 1/4 turn quick attachment.

Give Gemtech a call. They have three systems: threads, QD (Bilock), and HALO (any NATO standard muzzle device). The big disadvantage of threads is that if you don't use heat-resistant locktite, they can loosen while shooting. The different types of QD mounts have tradeoffs, too.

If I were to buy some cans, I would definitely use the Bilock. More accurate (repeatable) than the HALO mount, and more servicable than locktited threads.

I think the quick detach models are better than the threaded ones. My Mark 23 suppressor tends to unscrew itself after a few shots. A model with a locking mechanism like Gemtech's Bi-lock or TROS tri-lock won't come loose with use.

The only downside is the QD flash hider will most likely be permanently attached. Gemtech recommends letting them install the adapter to make sure the bore is centered correctly, or you might get baffle strikes from a lopsided FH/adapter.

It kind of makes me wonder why nobody makes self-tightening suppressors (helical baffles). Then you could just screw them on and they wouldn't come loose.

Zak, one issue might be over-tightening. As the barrel and suppressor heat and expand, possibly at differant rates, tighten, then cool, you might end up with a permanently mounted supressor.

I imagine a helical baffle would be less efficiant as well.
