Can I keep my AR 15 mags loaded?
It is possible to keep AR 15 mags loaded. The question is in the wearing-out of the spring, which happens in both cases: frequently loading /unloading the magazine or leaving it loaded to full capacity for long. The important thing while storing the loaded mags is the duration: if it is a long period (more than 4 months), it will cause a slow loss of spring tension some amount over time.
Will a M16 magazine fit an AR 15?
Standard M16 /STANAG mags are usually compatible with all US market AR15 clones. Under the NATO standardization agreement, they also fit many other rifle designs: 5.56 mags can work in M-16/AR derivatives, as well as in the British L85A2/L86 and the Canadian C-7. These firearms are compatible with STANAG magazines AR-15/M16 type rifles, CAR 816, AAC Honey Badger PDW, Colt M16 & M4, Barrett REC7, ArmaLite AR-15, Diemaco C7 / C8, and many others.
How many rounds does a standard AR 15 magazine hold?
There are 20 or 30 rounds, staggered-column placed in the detachable box magazines of Colt AR-15. If such quantity of the rounds is inappropriate or doesn’t correspond to legal limitations, it’s better to use magazines with a low-capacity of 5 or 10 rounds, for example, for hunting or bench rest shooting.
What calibers fit in an AR 15 magazine?
The standard AR magazines hold the 5.56 mm and. 223 rounds. The 300AAC (300 back out) rounds will be compatible with the standard mags, but it’s necessary to have a different barrel because of the bigger bullet diameter. There are three big calibers: .50 Beowulf, .450 Bushmaster, and .458 SOCOM.
What is the most accurate AR 15 caliber?
The 6.5 Grendel is considered the most effective cartridge, created for AR-15 due to its hard-hitting, 1,000-yards well-performance, and efficacy for hunting. LaRue Tactical OBR in 5.56, made by the AR factory, provides precise shooting as well. Both cartridges 5.56×45mm and the .223 Remington is compatible with the AR-15 rifle.

Try to choose trustworthy companies, and check the genuineness of the product. #1 Magpul PMAG M3 is one of the most well-known and reliable AR-magazines for an affordable price on the shooting gear market. If you use AR15 rifles for. 223 or 5.56, the same mags will fit them. Orlite mags from Bushmasters should be double-checked, because of known malfunctions with them, but excluding those cases, they operate well. Remember that one of the most important mag’s features is anti-tilt follower, providing good work for the bolt to pick it up. The best spring material is stainless steel to be resistant to dirt, debris, and corrosion. Long-lasting magazines have a durable polymer body; non-quality casing material can split at the spine, so pay attention to the producers’ reputation while buying the mags.

My love of guns is in my blood, since childhood I have spent hours enjoying the beauty of guns and adored going through their parts.

Tactical accessories are another passion of mine that I could write about endlessly - my house and garage are full of tactical gadgets, luckily my family shares my interests.

I'm infatuated with traveling that's why work at one place with a daily routine and standard schedule is not for me. I prefer copywriting and English tutoring as a freelancer. I live in a male family among constant talks about cars, guns, hunting, fishing, and, of course, dinosaurs 😊.

My husband is an obsessed hunter, and my two sons are fans of «Demolition Ranch» of YouTube blogger Matt Carriker. They are my best consultants about weapon and all-around ammunition topics. All together we share a love for adventures. Every camping or mounting hiking trip is a "small survival", giving irreplaceable experiences. Nothing can be better than the satisfaction of observing wild nature.

Motto: «Born in Ukraine, made is the USA».
