Pasted below find a forward from one of our customers
containing a couple of interesting links related to this product.

Dan,
Per our phone conversation on Friday, I've pasted two links below that pertain to Aero Precision lowers.  One is a general piece on the company and it's manufacturing techniques.  The other is the one w/ comparison photos of Colt, Stag and Aero lowers.  I look forward to seeing the AP lowers in person.
 
Best regards,
 
B
