Good for a 9 millimeter Luger conversion 22/04/2018
I bought this and have been using it with my 9 millimeter Luger AR-15 upper. It works great with full metal jacket brass ammunition. I think I have fired a little over 125 rounds through it without problems using twenty round ASC 9 millimeter magazines. It does not hold the bolt open when you fire your last round out of your magazine which I really do not care much about.
The one thing I do not like about the AR6951 9 millimeter Conversion Unit Adapter is to make the conversion permanent you would need to drill a small hole in your AR-15 receiver (minus one star for this). I did not bother with any hole drilling and it makes magazine changes more difficult as the conversion unit part will come out of my AR-15 magazine well when I push my magazine release. I just use it for target shooting and training anyway. Not really much of an issue when you have nineteen to thirty rounds to shoot.
9 millimeter is a great round to train with for an AR-15 for about 60 yard distances and closer. It is much cheaper to shoot than .300 AAC Blackout or 6.5 x 39 Grendel ammunition. You could use a 9 millimeter carbine in self defense but I generally prefer a more powerful round.
Unit is missing Bolt Catch Lifter 05/05/2017
Very happy with the fit and finish of this unit. However this unit is supposed to utilize a bolt catch lifter that eliminates the need for the Colt extended bolt catch. It not only is not included with this assembly, but Brownells does not carry it either. I will search for this part, but in the meantime, I will have to purchase the 9mm Bolt Catch in order for the last round bolt open to work. It looks like it should work, but we will see.
