Lil Rice Muncher from United States, TX Public Profile
Was able to tighten down my castle nut and bcm end plate onto my aero lower with ease. I tried the avid wrench before this and didn't like it. Slipped a few times. The magpul one just seemed to fit the notches on the castle nut just a little better for me.
Rock solid buffer tube. I had the BCM QD end plate and they both mate well to my aero precision lower. I love DD but had trouble centering the tube and qd end plate when tightening castle nut. with the bcm set on the other hand, it was quick and painless!! I will be using BCM tubes and end plates from now on with my future builds!
I love this BCM end plate. The rearward protrusion fits very nicely into the lower receiver and holds steady when tightening castle nut. The knob also fits well into the buffer tube notch so there's minimal play compared to other end plates that i've used in the past. The qd socket also protrudes a bit and is easy to access. the sides are flush and aligned perfectly with my aero precision lower.
I know a lot of people are high on MK18 10.3"s and they are absolutely great guns, but just a little more with this 11.5" makes a monumental difference. There is quite a bit of data and research out there to demonstrate this. With that being said, this upper has been rock solid for me. I mated it with an aero gen 2 lower and it fits perfectly (though i had to adjust ever so slightly the extra feature tension screw at the bottom of the receiver/inside pistol grip area). It does come with a vertical foregrip so - just a fair warning - please understand the law behind putting one of those on an AR pistol before moving forward. This upper is lightweight and rock solid with daniel defense's track record to back it up. I can't recommend it enough and this has become one of my favorite rifles easily!
I saw a couple reviews on here questioning the authenticity of their castle nut. Mine came in a cheap zip lock bag and I questioned it as well, but I have a DD rifle already and the two castle nuts are identical. Appears to be good quality.
I got this on my AR pistol. Keep in mind that you cannot put a VFG (vertical foregrip) on an AR pistol or it converts it into an SBR. Check with your state and local laws and regulations though. I like the KAG in particular because it gives you a little more to grab onto when pulling in the rifle instead of a standard handstop. This is plenty durable and doesn't move when in place. Does the job well.
Some hot stuff right here. It goes bang harder than my .223 round. Can't complain. I don't recommend this for general home defense scenarios as you'll likely overpenetrate but it's some really good ammo regardless!!
Sold construction and also includes a mount. A great value. Very easy to adjust controls and easy to see dot. Incredible battery life. I highly recommend if you're not trying to spent a lot of money on an optic.
Highly recommend this sling!! The padding is very comfortable. This sling is super adjustable and it's very easy to do so. There's a tab that allows you to do this on the fly. It's very useful so that you can use your rifle for different purposes and adjust to your environment. This sling was recommended to me by john lovell on youtube (warrior poet society). he's ex-military and every piece of equipment that he's suggested has not done me wrong including this sling. I would definitely give it a try.
