SOCOM Looks to Ditch 7.62 NATO For Better Long Range Performance
7.62 NATO in favor of a lighter and better-performing rifle in a 6.5
Special Operations Command is exploring a new caliber for its
semi-automatic sniper rifle needs and upgrading one of its bolt-action
sniper rifle systems.
Maj. Aron Hauquitz told Military Times Tuesday that SOCOM is in the
preliminary stages of exploring a sniper rifle chambered in the 6.5 mm
caliber. The two commercially available rounds being evaluated are the
.260 Remington and the 6.5 mm Creedmoor.
The 6.5 Creedmmor has become very popular with civilian shooters. Many
manufacturers now build rifles for the caliber and ammo to go with it.
I'm a fan of the M-16 round but it isn't meant for a long range sniper
When I read some of the ex-military blogs the M-16 is not well liked.
The M-14 became the superstar in Iraq and Afghanistan and finally received
praise and recognition it deserved as an excellent combat rifle.
I have some Marine friends that had to turn in their M-14 when the M-16
arrived in Vietnam. They will hate the M-16 to their dying day but
remember that the M-16 had several major problems at this time. By the
time I got there the bugs had been corrected and the M-16 was an excellent
weapon. The main complaint I've heard from men that used the M-14 is that
it was uncontrollable when firing on full automatic. I've fired the M-14
but never on full auto.
Unfortunately the M-16 suffered from a bad reputation due to early
errors which were corrected later.

During the early part of its career, the M16 had a reputation for poor
reliability and a malfunction rate of two per 1000 rounds fired. The
M16's action works by passing high pressure propellant gasses tapped from
the barrel down a tube and into the carrier group within the upper
receiver, and is commonly referred to as a "direct impingement gas
system". The gas expands within a donut shaped gas cylinder within the
carrier. Because the bolt is prevented from moving forward by the barrel,
the carrier is driven to the rear by the expanding gasses and thus
converts the energy of the gas to movement of the rifle???s parts. The
bolt bears a piston head and the cavity in the bolt carrier is the piston
sleeve. It is more correct to call it an "internal piston" system."
This design is much lighter and more compact than a gas-piston design.
However, this design requires that combustion byproducts from the
discharged cartridge be blown into the receiver as well. This accumulating
carbon and vaporized metal build-up within the receiver and bolt-carrier
negatively affects reliability and necessitates more intensive maintenance
on the part of the individual soldier. The channeling of gasses into the
bolt carrier during operation increases the amount of heat that is
deposited in the receiver while firing the M16 and causes essential
lubricant to be "burned off". This requires frequent and generous
applications of appropriate lubricant. Lack of proper lubrication is
the most common source of weapon stoppages or jams.
The original M16 fared poorly in the jungles of Vietnam and was infamous
for reliability problems in the harsh environment. As a result, it became
the target of a Congressional investigation. The investigation
The M16 was billed as self-cleaning (when no weapon is or ever
The M16 was issued to troops without cleaning kits or
instruction on how to clean the rifle.
The M16 and 5.56??45mm cartridge was tested and approved with
the use of a DuPont IMR8208M stick powder, that was switched to Olin
Mathieson WC846 ball powder which produced much more fouling, that
quickly jammed the action of the M16 (unless the gun was cleaned well
The M16 lacked a forward assist (rendering the rifle inoperable
when it jammed).
The M16 lacked a chrome-plated chamber, which allowed corrosion
problems and contributed to case extraction failures (which was
considered the most severe problem and required extreme measures to
clear, such as inserting the cleaning-rod down the barrel and knocking
the spent cartridge out).
When these issues were addressed and corrected by the M16A1, the
reliability problems decreased greatly. According to a 1968 Department
of Army report, the M16A1 rifle achieved widespread acceptance by U.S.
troops in Vietnam. "Most men armed with the M16 in Vietnam rated this
rifle's performance high, however, many men entertained some misgivings
about the M16's reliability. When asked what weapon they preferred to
carry in combat, 85 percent indicated that they wanted either the M16 or
its [smaller] submachine gun version, the XM177E2." Also "the M14 was
preferred by 15 percent, while less than one percent wished to carry
either the Stoner rifle, the AK-47, the carbine or a pistol." In March
1970, the "President???s Blue Ribbon Defense Panel" concluded that the
issuance of the M16 saved the lives of 20,000 U.S. servicemen during the
Vietnam War, who would have otherwise died had the M14 remained in
service. However, the M16 rifle's reputation continues to
