I’ve got 2 Lantac blast mitigating devices (BMD) with A2 collars for both. These fit your standard AR15 platform. Not for 308. These are clean. Took them off after I received my cans from jail. Also have some muzzle brakes. Lantac dragon 1/2x28 thread, no crush washer available. Lantac dragon for 9mm MPX LH thread. Precision armament M4-72 and a Hypertap both for .223/5.56. Send me a message for prices or send me an offer. Located in Prosper, work in Dallas. Cash or Zelle and local pick up only, no shipping. Not looking for trades.
