Just an update that NDS (Nodak Spud) lowers are RDIAS compatible as-is, and RLL compatible with two small clearance cuts at the back radii of the fire control well - providing an extra 1/8" clearance for the link to move, as in this clearance cut photo

Well, I am going to try just that here this coming weekend with a 5d Tactical jig on a v7 lower. I will report back. V7 Lowers are high shelf by 3/64ths of a inch. Why? Apparently for export issues. |

Aero Precision best fit that I have found in 27 years, that and preban Colt A2. Low shelf/high starboard side wall both. BCM is low shelf but starboard forward retaining wall low and RDIAS had a tendency to tilt in the receiver requiring shimming for a tight fit with the upper lug.

To build on the DIAS list a Broadhead Armory DIAS was used in the following:
Aero AR15 Gen 2 Lower Receiver, Special Edition: PEW works perfectly! Current 2018/2019 production lowers from Anderson also work. My old pre-ban Bushmasters should work as the fit is equal to the Aero's and Anderson's. It would not drop into a POF P-415 billet lower or ARCOM billet lower, they're both too tight and will not seat completely. Should be simple to enlarge the width of the pocket in each so it would fit and both are low shelf. Another possible is the PWS MK1 MOD2. It's low shelf and the DIAS fits but the profile of the pocket doesn't retain the DIAS and the tensioning screw / plunger would have to be adjusted or removed. Because theres no "bump out" on the right side of the pocket the uppers rear lug would have to hold the DIAS in place. |

I don't see any actual measurements of the pocket / shelf depth so I grabbed a dial caliper. High shelf (PSA and an old PWA) measured .500" from the deck to the shelf. Low shelf (Bushmaster and Aero) measured .630" from the deck to the shelf. Hope that helps given there are plenty of new companies producing lowers since this thread started. Please note I did not measure the width of the pocket so that up to you to determine if an individual lower is suitable for your LL or DIAS. |
