Really Impressed With The QualityI received all my order on Tuesday the 5th. I got it all assembled and am really impressed with the quality.

The insert you provided concerning ammo was spot on. I found Winchester ammunition will not work, nor will Rio, and other specialty brands. You can add Federal game loads, Estate, and Fiochi brands among those that will fit the magazines. The Estate brand functioned particularly well. I recommend that you should inform your customers that overall length should not exceed 2.25 inches.

Thank you for your great customer service. I have purchased a significant amount of merchandise from various different suppliers and your customer service is by far the best. I look forward to more purchases from you in the future.

Fun So FarPicked up my upper at UPS Friday, fitted it to a DPMS lower and got to the range Sunday. The range is indoor and only allows slugs from shot guns. Remington 2.5 inch slugs worked great as did some Hornady Critical Defense. Took it out to the woods for a little armed recce (squirrel hunting) discovered that not all 2.5" 410 ammo is equal. Winchester AA HS is over length for the magazine and the chamber. Fortunately my other 410 wont care. So far I'm impressed with the workmanship and look forward to more range sessions before the snows fly and deer season gets here. Written by Curtis Givens on Mon 28 Oct 2019 10:39:56 PM GMT
