Mason from United States, MN Public Profile

Please note that this magazine ships with a block inside of it that restricts the capacity to 5 rounds. This is so that communist states like Illinois and California can purchase these freedom seed receptacles.

The block can easily be removed using a punch, dental pick, or another similar tool.

After removing the block the magazines works great. Easy to disassemble and reassemble.

I like these pins. Easy to install, it came with all the tools that I need to install it, fits flush on the rifle, and priced agreeably. If you are in the market for anti-walk pins, this is a very safe choice.

I purchased this to make an AR-9, and this was the only magwell adapter (or any lower receiver option) for M9 Baretta magazines that I could find. Luckily, it's everything that I want. Easy to install, durable, LRBHO compatible, works with all of my M9 magazines (m9a3,m9a4, military surplus m9 magazines) and it caused 0 malfunctiones in my first 500 rounds through the rifle so far. If you want to build an AR-9 that takes Baretta magazines, this is your solution. I highly recommend it.

Notes: I am using a PSA lower receiver, a Geissele 2 stage trigger, an Aero precision upper, Ballistic advantage barrel, and JP enterprises combination 9mm BCG and silent capture buffer system with 2 tungsten weights. If you are struggling with research and trying to build an AR-9, I hope this helps.

Anyone who has ever built an AR-9 knows that getting it to run is challenging. I did a ton of research before building my AR-9, and I did not see this bolt combo being promoted very much, but I also didn't see any negative reviews. I took a chance on it, and I am happy with my purchase.

Some things to note: When you are building an AR-9, you want the combined weight of your bolt and buffer to be 24-26 oz. This way, the weapon will function comfortable with most ammo, both suppressed and unsuppressed. The way you get to that sweet spot with this buffer is 2 tungsten weights, 3 steel weights. You can also go for 3 Tungsten weights and 2 steel weights, and you should still be safe.

This bolt is compatible with LRBHO. I am using it in combination with the stern defense magwell adapter so that I can use m9 Baretta magazines, and I have had 0 malfunctions in the first 500 rounds. I am using a ballistic advantage 16" 9mm barrel. I have shot it fast, gotten it hot, used the cheapest crappiest ammo I can get my hands on, and this bolt chews through everything.

the recoil on this bolt feels very good for an m9. The spring is silent in the buffer tube, which greatly helps the feel of the rifle. It does have a bit of recoil, but the impulse is consistent, so you can run it fast with training. I use a Geissele 2 stage trigger, and have had no issues with light primer strikes.

I purchased this red dot to run as a 45 degree offset sight on my duty rifle. A couple of things to note:

The optic's controls were not very intuitive. When the optic is on, the brightness can be controlled by pressing the buttons on the side of the optic. When it is off, the dot remains on because of the solar panel feature on the optic. The brightness of the optic when powered by the solar panel cannot be adjusted, and I sometimes do not know if it is on or off.

The shake awake feature is unreliable. There are many times when I grab the rifle off my shelf and look down the sight to find that it has not powered itself on. I have to hit it forcefully to get it to power on. THAT IS A NO GO FOR DUTY USE.

The optic has a strong blue tint, and the glass is not clear. The optic has bad issues with glare when in the sun, and I get double vision when looking through the optic with both eyes open.

Some pros for this optic is that the dot is easy to acquire. It holds zero well, and it is durable. They battery life is also excellent, and despite what warrior poet said, you can change the battery on it without removing it from your gun.

If you want something cheaper than a Trijicon, this is a decent option. I would not recommend this for any kind of duty use. I will not purchase this optic again.

This muzzle device is designed to do exactly one thing: Delete your recoil. I run it on an 18' AR, and it was a night and day difference going from an A2 flash hider.

A couple of things to be aware of if you are going to buy: This muzzle device directs all of the concussive forces of the muzzle behind and to the side of the shooter. For the shooter, it is an extremely pleasant experience, but your spotter might not like it.

The first time I shot my rifle after installing this, I put my hand on my bipod leg to steady it on a table (I was at an indoor range, and finding a place for my hand can be awkward in places like that.) When I fired the rifle, The gasses and un burnt powder coming out of the system peppered my hand noticeably. It was not painful, and I could not feel it while wearing a glove, but if you are a shooter who likes to hold their bipod when they shoot it is good to be aware of that.

Despite being a very long compensator, I had no baffle strikes, and the installation was very easy.

This is not a product that everyone will like, but it is also not designed for general purpose shooting. This is not a compensator that you put on your rifle when you are trying to make friends. This is something that you use when you want to delete recoil. Even with a 6 power scope, I barely felt it move. I will probably buy another one in the future.

This is my default optic for when I want a red dot. There is nothing wrong with it. The glass is clear, the battery life is great, the shake awake technology is reliable, it's easy to use and it's durable.

I really like the glass in this optic. It has no tint, it does not cause double vision when shooting with both eyes open, I never have issues with glare from sunlight, and the dot is small and crisp enough to do the job. I run this optic when I play airsoft, and I have never had any issues with it.

I have also run this optic on shotguns, AKs, and ARs. The low mount that it comes with is ideal for mounting to AK platform rifles and shotguns like the Benelli M4. I have had no issues with zero shifts, even when I drop the optic.

You would have to be a real optics snob to turn your nose up at this optic, especially at this price point.

I am not a trigger snob. I spent my Army career using a milspec trigger, and coming off of that, everything feels great. This trigger has a light, consistent single stage trigger pull that precision shooters will like, but the reset is a bit grindy, and there is not a lot of spring tension to help get it back into position. If you are trying to shoot fast, there are better options. If you want a light trigger for precision shooting, this is a great option. I would not recommend for any kind of duty use.

As an army guy, I was wishy washy about purchasing an ACOG. The optic is great, but I like my length of pull, thank you kindly. This product was the reason that I finally pulled the trigger on it, and I gotta say it was everything that I wanted it to be. A full 2 inches of additional eye relief makes a huge difference, and then having the thumb screws facing away from you means that the optic will spend less time getting snagged on your kit. This is a must have for all acog users who don't like straining their necks. If you are active military looking for a way to make your life a bit better, take your rear iron sight and put it in front of your ACOG, put your ACOG on this mount, and then mount the ACOG as far toward you as you can get it. You will go from fumbling to get a sight picture to having your eye sucked into a perfectly crisp image of a soon to be dead terrorist.
