All of those problems, mostly stemming from bad magazines, inferior gunpowder, and a misguided notion that the weapons was self cleaning, are gone in current incarnations of the rifle.

Every attempt to find a replacement has borne little fruit. Over the past 15 years, the civilian firearms industry and special operations units have developed a number of innovative parts for ARstyle rifles that leave M4 and M16 variants looking rather dated. With both the Army and Marines Corps potentially upgrading their rifles, here are a few components that will bring theses weapons to the next level. The Picatinny rail standard was a revolution when it was introduced in With a system of standardized T-shaped ridges and gaps, Picatinny rails allowed for truly modular accessories.

This design allows for plenty of attachment space, but has two major flaws. The military actually already has free-floating rails in the inventory; this Daniel Defense quad rail system is in use by many units in Special Operations Command. But this brings out second major issue: The quad rail design is bulky, heavy, and uncomfortable to hold. Tube rails are significantly light, reducing the overall weight of the weapon.

Some tube rails are less than one inch in diameter, making them the rail less bulky and easier to grip using modern techniques. Finally, tube rails allow as much attachment space as needed using bolt-on sections of Picatinny rail, or newer, low-profile direct mounting interfaces like Keymod or M-LOK.

The user only needs to mount enough rail space for each attachment, or simply direct mount them to the handguard. On the M4 and M16, the regular gas block is fixed. This was fine when those weapons were first conceived, but times have changed. An adjustable gas block allows the shooter to easily regulate the amount of gas that flows through the gas tube. This has two main applications for military use. First, it makes using a suppressor significantly easier, as the user is able the regulate the gas systems to ensure the weapon cycles reliably.

Second, it allows certain types of specialized ammo to run through the gun smoothly; the ability to reliably shoot precision ammo would lend both the M4 and the M16 to use as a designated marksman rifle when dedicated platforms like the Mk. Both of these would provide valuable capabilities. They use a mechanism that allows the suppressor to be quickly slipped over and secured onto an existing flash hider, compensator, or muzzle brake.

While the silencing capabilities of suppressors have been vastly overstated in popular media, they do provide a limited measure of stealth. More important is the safety role of suppressor; it makes firing the weapon hearing-safe, particularly indoors.

Without a suppressor, a shooter must wear hearing protection to avoid temporary and permanent hearing loss. Advances have been made in other types of muzzle devices. Some of these improvements have already been adopted by special operations forces. This is more of an improvement for the M16 than the M4; the M4 already features a six-position adjustable stock. The M16 has a fixed stock, which was the norm when it was first introduced.

Most service members wear hard body armor systems in a combat zone. Many will be constantly moving it out of various vehicles and aircraft. Retractable stocks, like the one above developed by Naval Special Warfare Center Crane Division, allow the user to select whatever length of pull is most comfortable. Retractable stocks also enable the rifle to be easily carried inside vehicles and aircraft.

The Army and Marine Corps could simply swap out fixed stocks for the standard M4 and Crane stocks already in inventory, or they could upgrade both guns with a new commercial stock design. Companies like MagpulB5 Systemsand Vltor offer enhanced stocks with quick-detach sling points, battery storage, and other features.Sign in. Sign in with.

These are two-piece handguards that most M4s use, as they were included in the original designs. They also tend to be very affordable in comparison to the alternative. Of this variant, polymer handguards have a metal heat shield on their inside. Railed drop-in handguards usually have four rails that allow you to mount various accessories to your weapon.

These provide a great customization choice for your M4 build. This lets your barrel float and may improve your accuracy slightly. There are some key factors to keep in mind during your browsing or shopping process.

These are important features that directly affect how a handguard can change your weapon operation and its performance during shooting. Some handguards will add to a military or custom appearance. Consider what kinds of accessories you might use. Railed handguards have a greater capacity for attachments, for example, so something like this might have you narrow your search criteria.

Some handguards affect accuracy positively or negatively.

This is a great standard handguard that should work with most M4 builds. Additionally, you gain the capacity to add some attachments. Workable accessories include Picatinny rails or some M-LOK additions that you can find on various sites.

There are slots at three different positions to allow for ultimate flexibility and customization. There are also extensions at the front and sides to extend the heat shield over the gas block; which could come in handy in certain high-humidity environments.

This is a classic, affordable model that combines the heat resistance of a polymer construction with the accessory function of a rail model. This allows you to modify your weapon the way you like it while still providing excellent protection for you and the weapon. This is on the other end of the spectrum from the previous product It brings some excellent value for the money as a free float model, which means that it rests above the upper receiver.

Anti-rotation tabs help keep it locked into place even under heavy fire. The material is a high-grade aluminum, which can resist some heat but isn't quite as good as a polymer model in our first review. However, given its total customization, it's clear that this item is more for builds that have a high mod count in mind. The AIM Sports handguard is made from aluminum in a free float mold. This is very much the opposite of the previous handguard. It's small, compact, and ideal for simplistic M4 builds that aren't going to make much use from a bunch of mods.

It's made from a polymer compound that's already ideal for resisting heat as opposed to an aluminum alloy. A single heat shield is included to defend your hands when the weapon is running hot. This minimalist design also allows it to be sold for a great, affordable price and keep the weight of your weapon low.

The lack of modularity should be seen as a feature, not a flaw, since some folks will want a standard-issue M4 and won't bother with scopes or attachments very much in the first place. The Double Star handguard is a compact, minimalist piece that provides protection against heat and ignores the possibility of many modifications.

This is another dual-purpose handguard that fulfills a lot of needs at once.Iceland is a spectacular and beautiful country. We really enjoyed the trip to Akureyri. The whole country is an undiscovered paradise. We bought lots of mementos and will carry beautiful memories also. We made the right decision to come to Iceland rather than the more crowded Nordic countries. We would love to come back if the opportunity presents itself.

We did come to the office to meet you all but when the office was shut we remembered it was Sunday. Merry Christmas and Happy New Year. That was such a success that we felt confident our good experience would be repeated, it was!.

We just completed our Drive It Ourselves Tour of Norway. We added 5 extra nights to the standard 12 night tour and found that we needed all of them to see and do all that was available.

The itinerary was well thought out and gave us a thorough look at central and southern Norway. The rental car was acceptable and Avis upgraded us at no extra cost. All the hotels were above our expectations. We rated all of them 4 or 5 and we have seen a lot of hotels in 26 years of travel. The hotels were all in the center of town and within walking distance of most attractions. The breakfasts were varied and set us up for the whole day. We highly recommend Nordic Visitor. This past summer we spent a week in Iceland following the "South at Leisure" self-drive tour arranged by Thordis of Nordic Visitor.

The entire experience was first-rate. Every accommodation that was arranged for us was beautiful, every meal was amazing, all of the people we met were friendly and accommodating, and every day was memorable. We not only enjoyed the sightseeing, we got to ride horses, hike and snowmobile on glaciers, and snorkle in Silfra.

We also indulged in "underwater massages" at the Blue Lagoon. The weather was cool and rainy most days, but the sunlight lasted all night, so every day felt like two days of vacation.

I highly recommend visiting Iceland, especially since it is only a 5-hour flight from NY, so you don't even have to worry about jet lag.

I also recommend using Nordic Visitors - they were there for us every step of the way - even when we changed our minds or changed our schedules. My husband and I chose the Iceland Express tour in mid July. Our travel agent, Sigfus, was very thorough in the planning and everything went very smoothly. We chose the mid level or "comfort" option and all the accommodations were clean and comfortable.

The rental car was great and very fuel efficient.
