AR-15 (Bushmaster M4)

This is my primary CQB weapon. It started as a Bushmaster M4-type rifle, but it has been extensively customized. It is quite accurate, incredibly easy to control, and target acquisition is very fast. The 5.56x45mm (or .223 Remington) cartridge is not ideal for self defense, but it is no slouch.

The upper and lower receivers and the bolt carrier group are made by Bushmaster. It has an A3 (flat top) receiver, a telescoping rear stock, an Izzy flash suppressor, and 30 round magazines.

This rifle fires either the 5.56x45mm NATO cartridge or the .223 Remington, the two being almost identical. This cartridge has excellent ballistics, shooting flat and accurate. In addition to home or personal defense, this weapon could be used for larger varmints and smaller game.


I now have a Trijicon RX06-23 reflex sight on this rifle. It uses a combination tritium and fiber-optic light source which is always on, requires no battery, and automatically adjusts to surrounding light levels. This version of the sight uses a 12.9 MOA triangle reticle. I hope to use the upper point of the triangle for more precise shooting.

I also have a Mueller Eraticator 8.5-25x50mm scope that I can attach as needed. However, I think I would like to find a smaller scope that would be better suited to tactical uses. Ideally, that would be a 2.5-10x scope with a short overall length and tactical turrets.


For self defense, I had selected the Wilson Combat ammunition with the 65gr Sierra GameKing bullet. It is "match grade tactical ammunition" that uses the bullet I believe to be most ideally suited to my rifle for defense applications. I have tested it, and it groups well for factory ammunition. I need to stock up and have several loaded magazines ready.

Unfortunately, they stopped making it.

Hornady has released a line of Critical Defense Rifle ammunition, which uses FTX bullets. In this caliber, they have a 55 grain and a 73 grain variety. Nosler has also released an interesting 64 grain bonded bullet for defense. I have tested these in this gun, and I will think about possibly selecting one for personal defense.

55 gr. Hornady Critical Defense: I test fired a single 5-rd group, and it measured 1.454" @ 100 yds.

73 gr. Hornady Critical Defense: I test fired a single 5-rd group, and it measured 2.624" @ 100 yds. No keyholing.

64 gr. Nosler Defense: I test fired a single 5-rd group, and it measured 1.829" @ 100 yds.

How much accuracy do I really need for defensive ammunition, given that I'll be using a reflex sight with a 12.9 MOA trianglular reticle? For CQB, accuracy is not really a high priority. Maybe it would be a different story if I had a decent optic mounted on the thing. So really, I should probably choose the round I believe to be most effective (as long as they don't keyhole).

.350 Legend

I have ordered (or, allegedly, "pre-ordered") an upper in .350 Legend. I have been advised to expect shipment sometime in May of 2019.

I have already received an optic for this rifle, a Konus M30 1.5-6x44mm scope with an illuminated center dot. It is an updated version of what I have on my PTR-91, having done away with the ridiculous external turrets and locking bars, as well as the internal bubble level.

However, the scope seems fogged, and the optics aren't very great in the first place. If the .350 Legend proves to be accurate and reliable, then perhaps I should upgrade the scope to a Burris MTAC 1.5-6x42mm Riflescope with the Ballistic AR reticle (200439).

I also have a set of Warne rings ready for it.
