Heard several differing opinions on the reliability and accuracy of this conversion but finally bit the bullet (so to speak!) and bought one. Found a brand new unit with mag on Gunbroker and won for $135 plus $5 shipping.
This is a late production parkerized steel unit that looked like it was pretty well made. Magazine looks much like a standard AR15 polymer and loaded easily.
Parkerizing was a litttle gritty out of the box so I hosed down with Mobil 1 and buffed with a towel and re-lubed. 30 seconds to remove bolt and carrier from my flattop M4 Armalite upper and install. Ditto for install into my Colt
m16A1 upper although the feed ramp is a bit sticky on that one.
Ran about 250 rounds of cheap bulk Remington ammo through both uppers with zero jams or feed problems. Accuracy was acceptable in both with the M4 actually pulling tighter groups. Checked chamber and barrel after shooting and saw only a little powdery residue and some dirty Mobil 1 from my over-lubing.
IMHO this is a useful and practical accessory for practice shooting and plinking with an AR15. Does anyone have any long-term experience with
this device?
