Slow delivery, but...
Delivery was very slow, but, it's $50 cheaper than anywhere else, plus free delivery. Product came in perfect condition, so how can you complain? Thx AU!

Great product. Fits AR-15 uppers onto the AR-10 lower. Looking forward to firing it for the first time soon.

Fast service at a fair price
I received my ordered Colt 5.56 adapter conversion kit faster than expected. The unit fit perfectly in my MARC901.

Works great
I got the kit for my Modular Carbine lower and used it with an LMT MRP 5.56 upper and a Colt LE6920 5.57 upper with no issues. Works as advertised. I knocked a star off since I was expecting the retail card backed version of the product, and instead received the item in a zip lock bag. Not a big deal since I was planning to use the kit immediately, but it would have been nice to know if it was retail or OEM up front.

Colt LE901 Conversion Block for 5.56/223
This conversion block really rounds out the usefulness of this rifle. It not only allows me to use this heavy built lower with the 5.56 round, but also with my 50 cal Beowulf upper.
