warthog984 Posted August 10, 2014 Report Posted August 10, 2014 RRA pins are longer than DPMS-based and Armalite-based pins, too. warthog, can you measure your front pivot pin and provide the length? I can compare that to an RRA pin and see if it's the same. That way, we'll know. <thumbsup> Here is what I got for measurements: Aero Pins Takedown Full length 1.1655; Below the lip down 1.0520 Pivot Pin Full length 1.7130; Below the lip down 1.5860 DPMS Pins Takedown Full length 1.201; Below the lip down 1.082 Pivot Pin Full length 1.64; Below the lip down 1.510 I purchased both the DPMS and Aero Pins. I ended up using the DPMS takedown pin and Aero pivot pin. The Aero takedown pin is to short. It sits just flush with the receiver. Don't ask my why they did that. My opinion is that they should have a note on when you purchase the receiver sets about the different length pivot pin. It is mentioned under their 308 lower parts kit that the pivot pin would be to long in a DPMS receiver. They also don't mention on their site that the lower comes with the bolt catch screw. The Forward assist comes with a screw rather than roll pin too. Did not mention that on the site when I purchased it. The only screw not provided was the 4-40 screw for the takedown detent.
jumpsteady Posted August 23, 2014 Report Posted August 23, 2014 Are the M5 upper compatible with a DPMS lower? I am considering getting another upper to go with my AP4.
98Z5V Posted August 24, 2014 Author Report Posted August 24, 2014 They now have the Cerakote FDE uppers, lowers and combo sets in stock. Prices on that combo set are DAMN good - $333. Great price.
AdamO Posted August 28, 2014 Report Posted August 28, 2014 True to their word... they now have bolt carriers with the forward assist. Wondering if they'll do a NiB version..
98Z5V Posted August 28, 2014 Author Report Posted August 28, 2014 ^^^ Very smart - very good ramp on that, almost like a ramped 9mm bolt carrier. Cuts down on hammer abuse during cycling.
AdamO Posted August 29, 2014 Report Posted August 29, 2014 Waiting for them to release the NiB version and I'll likely pop for just the carrier and switch my bolt over to it.
98Z5V Posted August 29, 2014 Author Report Posted August 29, 2014 You can pick this on up, and just send it to WMD Guns, and they'l NiB-coat it for you.
survivalshop Posted August 29, 2014 Report Posted August 29, 2014 The F/A notches are in the correct plane for there Upper F/A.
BadBoyBilly Posted October 31, 2014 Report Posted October 31, 2014 Heads up, the receiver sets are back in stock and are $288!!!
