This suppressor is in good condition and comes as shown. • Immediate Submission of Transfer...form 3 efile! • Pre86 Sample • Can Be Kept After Giving Up License • LE Demo Letter Not Required • CLASS 3 DEALERS ONLY According to the ATF paperwork, Heckler and Koch is the Maker of this Suppressor. This is a pre 86 dealer sample and can only be transferred to Class 3 Dealers. This is, however, the type of dealer sample which does not require an LE demo letter and can be kept by a class 3 dealer when giving up his license (just as if it were transferable). Again if you are not a class 3 dealer, you can not own this, so please do not bid. It is our goal that you are 100 percent satisfied with our product and transaction. The buyer will have a 3 day money back inspection period after this is received by your FFL. S/N: 01-004275
