I have an extra one of these. This muzzle brake is absolutely brand new and unused in the factory sealed packaging. It is priced at just $135 with free delivery. Payment would be by a USPS or bank money order or by Paypal. No further price reduction on this item and no trades are needed at this time. IMHO, it is the best all around muzzle device you can but on your AR, and the only other muzzle device to equal it is the KAC MAMS brake, at twice the price and I doubt you will find it at a better price The links below have some additional information on the item.
