I did a trade with bulletproof about two weeks ago and was very happy with the speed in which the transaction was done (we did not spend a week talking about it) we sent messages back and forth for about three days,and after making a full review of my G&G UMP .45 for him he was happy to ship first. I was able to ship my gun two days later and the whole trade process was done in a week;however,in being courteous he did forget to pack the battery he was charging for me,but quickly had it sent out the next day. It was amazing to see someone correct a mistake so quickly. Also,I know that the sig 550 he sent me came stock with a bipod that was not included when shipped to me,so I asked him about it,and he graciously sent it to me upon my request for it. Lastly,the gun functions exactly how he said it did,and I was aware of any flaws with it before the trade,which proves his honesty once again. 10/10 would preform another transaction with again.
