Welcome to the NoDak Spud LLC ® Retro AR Page We manufacture the highest quality reproductions of the M16A1, XM16E1, early 601, and AR-15 Prototype receivers and parts. Nobody in the industry matches our quality and attention to detail. ** WE DO NOT MAKE THE UPPERS OR LOWERS FOR BROWNELLS, ALL WE DO IS SUPPLY THE RAW FORGINGS** **WE HAVE ABSOLUTELY NOTHING TO DO WITH THE PRODUCTION OF THOSE PARTS**

**NEW POLICY** WE MUST HAVE AN UP TO DATE, SIGNED COPY OF YOUR DEALERS FEDERAL FIREARMS LICENSE ON FILE BEFORE YOU WILL BE ALLOWED TO PLACE AN ORDER FOR A FIREARMS RECEIVER

ALL FFL ITEMS WILL BE SHIPPED WITH "ADULT SIGNATURE REQUIRED"

In order to help you decide what "Retro" model you want to build, and what lower and upper receiver is appropriate, please go to www.retroblackrifle.com

Due to the difficulty in transforming "A2" forgings into "Retro" lowers, we have invested in several dedicated "Retro" style forging tools. This required substantial time and money to tool up for, but in the end, was well worth the effort. All NoDak Spud ® "Retro" lowers are made from these forgings. We know you will be very pleased with the finished products. Thanks, Mike and Harlan From top to bottom: NDS-16A1 NDS-601 NDS-XM16E1 NDS-603

A WORD ABOUT THE FIT OF OUR LOWER RECEIVERS: OUR LOWERS ARE MACHINED IN SUCH A WAY THAT THEY HAVE A TIGHTER FIT TO MOST UPPERS. WE RUN ON THE HIGH SIDE OF THE TOLERANCE, WE DID THIS ON PURPOSE. 99% OF THE TIME IT RESULTS IN A GREAT FIT WITH NO WIGGLE BETWEEN THE UPPER AND LOWER. SOMETIMES THIS MAY CAUSE PROBLEMS WITH SOME SURPLUS UPPERS OUT THERE. IF YOU ARE CONCERNED THAT THIS MAY BE AN ISSUE FOR YOU, PLEASE PURCHASE ONE OF OUR RETRO UPPERS AT THE SAME TIME, AND WE WILL HAND SELECT THEM FOR FIT AT NO EXTRA CHARGE. IF YOU ALREADY HAVE A STRIPPED UPPER YOU WANT TO USE ON ONE OF OUR LOWERS: YOU CAN SEND IT IN (AT YOUR EXPENSE) AND WE WILL MATCH IT FOR BEST FIT IT TO THE LOWER YOU ARE PURCHASING FOR NO ADDITIONAL CHARGE. WE JUST WANT YOU TO BE HAPPY!

FYI: WE DO NOT GUARANTEE COLOR MATCH ! This is next to impossible given all the variables that are involved. One of the biggest problems is the age and use of your surplus upper. If you need them to match perfectly we recommend that you order yours "in the white". And then send it and your upper to US Anodizing for a custom match.

The NDS-XM16E1 "Retro" lower receiver This is the version used "pre-adoption" in Viet Nam. After the Army fielded some XM16E1's, they decided to adopt it as the M16A1 (with some improvements). Please notice the roll-pin hole on the back end. It is sized to take a 3/32 roll pin just like the original. But, unlike the originals, it DOES NOT intersect the buffer tube by cutting through the threads. I felt that was unnecessary, and could cause more problems than good. Material is 7075 T6 The anodizing is done by Victor @ US Anodizing in his "XM" gray. NDS-XM16E1 receiver Price: qty 1 $160 shipped 2-5 $155 ea. 6-20 $150 ea.

"Battlefield Pick Up" Lowers and Uppers: For and additional $20 per part , Mike will hand polish an upper or lower to look like it has; "Been there, and done that" This is on top of the cost of the NDS receiver you are ordering. We can do it on any parts, but prefer to do it on our "blems", call in for current availability. Make sure you specify "HEAVY" (as pictured) or "LIGHT" scrubbing. "Heavy" will break through the hardcoat to bare white aluminum in some spots. "Light" will smooth out the surface finish and lighten the color. We try to bring out the bronze on the high areas without going to bare metal all over.

"Blem" Lowers From time to time, we have "blem" AR lowers available. They are usually cosmetic issues due to forging flaws or un-even anodizing. Occasionally it is a machining error. Sometimes it's a combination of things. These parts are fully functional, and offer the thrifty customer a way to save some money on his build project. All "blem" lowers will have a letter "B" stamped on the side of the pistol grip area. This stamping is done AFTER anodizing, and may chip the finish where stamped. However, this is covered by the pistol grip, and therefore, not visible. NEW PRICING SCHEDULE FOR BLEMS: There will now be a 2 tier pricing on blem uppers and lowers. Small anodizing issues and minor forging flaws are -$10 off ($150 shipped) Bad anodizing issues and larger forging flaws are -$20 off ($140 shipped) "Blem" Lower Receivers NDS-16A1B (gray) status: sold out NDS-16A1B (black) status: sold out NDS-XM16E1B (gray) status: sold out NDS-XM16E1B (black) status: sold out NDS-601B (gray) status: sold out NDS-601(no +) status: sold out NDS-15 status: sold out Please call to order 952-942-1909 There are NO FURTHER DISCOUNTS on "blem" lowers or uppers, and they cannot be combined with other products for quantity pricing.
