I think your logo at the top is too big, and doesn't leave enough room to display the stuff for sale.
I'd like to be able to click on any of the pictures of the stuff for sale and see a much bigger picture with better detail.
The "about us" page: Paragraph beginning with "Our goal is" is in all caps, WHICH MAKES IT HARD TO READ.
The "contact us" page: Your first two options are Complaint and Problem. Praise is the last choice. Kinda gives the impression you get lots of complaints and problems.
The "specials" page: Shows your lowers for sale. Includes the phrase "Also shown in the white for illustration purposes", but alas, that just ain't true.
Again, the more I click around on the site, the more that huge logo bugs me. Too much scrolling to see the real info because of that.
The "login" screen comes up huge for such a small amount of text. No password box, just a login box and an enter button. What's the purpose of this?
Someone else already commented about the pre-ban/post-ban language that's not needed anymore.
Home page " All orders are shipped ... USPS postal service." Since USPS means United States Postal Service, you then ship by US Postal Service postal service?
Comment on the restocking fee has FEE capitalized. Typo.
No privacy information statement - what info do you collect and what do you do with it?
On the complete firearms page, why mention that FET is included? 95% of people won't even know what this is, except for the .gov people who know they're exempt.
At the end of the description for the Tactical Master Charging Handle Latch - Made in Arizona, USA.sdfgdf. - must be a typo
References to "mil-spec" vary from "mil-spec" to "Mil-Spec" to "Mil-spec"
Description on your 20 round mag "An excellent
qualtiy steel mag."
Those are the most obvious things that I saw when reviewing the site. Any more detailed and I'd have to charge you.
