Frank –
I was in the market to replace my Kriss vector with a lighter .45 PCC. I was at a gun show and saw the Angstadt UDP-45 on the table. Knowing nothing about it I googled it and saw great reviews. Being it was a hometown manufacturer I went for it and made the deal. The fit and finish are great. All the controls are the same as a normal AR style rifle. I went to the range today and only have one complaint . It eats everything you feed it!!! No problems at all. I zeroed to 25yards. I was hitting steel to 50 yards. A lot of people were interested in this little gun. I went from a 8lb vector down to 4lb PCC. I was considering a CMMG, but I am glad I found you product. Keep up the good work. If you need a tester for your products let me know!!! Thanks again for make a great weapon. Cheers!
