We wrote about the Kel-Tec KSG back in April and our view of the bullpup design still hasn’t changed about enjoying the bullpup design and concept, the idea of having a full length rifle in a small package without the loss of accuracy and range of a short barreled rifle.

The rifle has a different ejection system than any rifle I ever seen and is patented by Kel-tec as a forward ejection system. The spent shells are ejected through a tube over the barrel of the weapon and slowly push each round out using the round after or if the weapons barrel is tilted down they can just fall out. One of the major advantages to this system is when firing next to someone you are not shooting hot brass towards them.

The weapon system is fully ambidextrous.

The barrel is threaded to allow for flash suppressor or sound suppressor.

The weapon and be field stripped much like the AR-15 platform by using a live round to push out the 3 pins that holds this weapon together.

Gepard M1 (name this gun 9-19)


Monday we posted a name that gun (Which Gunmart reblogged to his readers also. Thank you)

The Gepard M1 is a long range anti-materiel rifle.

Weight: 17.5 kg / 38.6 lbs.
Length: 1,570 mm / 61.8”
Barrel length: 1,100 mm / 43.3”
Action: Single shot
Caliber: 12.7×108, .50BMG
Effective range: 2000+ Meters

This weapon was designed in the late 1980s and was first used in service in 1990 by Hungarian army for destroying armored targets using heavy AP (armor piercing) rounds.

The weapon loads by turning the pistol grip up allowing for the operator to load a single round into the breech (The grip does not need to be fully removed to reload). The reason behind the single shot action was to reduce the number of moving parts to allow for extreme precision marksmanship.

Due to the heavy weight that the M1 has, the Hungarian snipers were instructed to leave the weapon if they had to retreat quickly and to only save the grip assembly rendering the gun useless.

“Due to the considerable size and weight of anti-materiel rifles and other support equipment, sniper cells operating in 2- or 3-man or larger teams become a necessity. The recoil produced by the employed cartridges dictates that these rifles are designed to be fired from the prone position. Bipods and monopods and muzzle brakes are used as accessories to employ these rifles as comfortably and accurately as possible. Firing several 12.7x99mm NATO, 12.7x108mm Russian, or larger calibers from the (unsupported) standing position or in a kneeling position would be very uncomfortable for the operator.”

Design considerations were:
”1. The 12.7x107mm cartridges muzzle energy is about 5 times more than the 7.62mm’s. The shooter cannot handle this without a muzzle compensator.
2. To efficiently use the cartridge’s energy, the barrel needs to be at least 1100mm long. (Muzzle velocity 850m/s). A conventional buttstock would increase the length to 1600mm [63″], too long for efficient battle handling. The rifle needs to be redesigned in ‘bull-pup’ style and/or collapsible stock or carried disassembled with quick field assembly possibility.
3. The rifle is too heavy to use without a bipod or tripod.
4. During firing while the bullet travels in the barrel the rifle moves backwards about 6-8mm. If this movement not purely axial, the accuracy will suffer. The rifle’s muzzle end has a tendency to jump up when the bullet leaves the barrel. If the muzzle jumps within the gas-reaction-zone, (200mm in front of the barrel for this caliber), the accuracy will suffer.
Overall the rifle’s recoil must not be larger than the Dragunov SVD Sniper’s, the accuracy and effective distance must be significantly better than the SVD’s, the rifle length must be less than 1500mm [59″] and lighter than 16kg. Two different design are necessary, one for the single shot version, the other for the semi-automatic rifle.
The following energy-amortization was considered in the design: The barrel is allowed to slide axially back 100mm against a spring force. This increases accuracy over fixed barrels and decreases gun recoil. A spring-loaded buttstock located in-line with the barrel also decreases the recoil. A muzzle break can be designed and installed to compensate for the remaining recoil.”

Top 10 Favorite Rifles

Top 10 Favorite Rifles

This week will be for Top Ten favorites of the Gears of Guns crew. It will be broken up into 4 categories: Rifles, Pistols, Bullet calibers and “other”.

if you have a gun you think we didn’t consider please feel free to share it with us.


The AR-15 is at the top of our list because it is for lack of better wording the ”Barbie” for men. This weapon system is highly customizable to fit the users wants and needs. 

PRO:  The weapon system can be changed to fit the shooter, everything from the caliber to the barrel length, to trigger group, letting the shooter find the perfect combination to fit them.

CON:  Possible malfunctions due to semi-auto action gas system causing them to break. Most of the cons we have for this weapon stems from size of caliber or internal firing mechanisms from different manufacturers.

Remington 700

The Remington Model 700 is number 2 on our list because of it reliability. The weapon has been used by both hunters and snipers. The weapon has been battle proven for years as the M24 Sniper rifle and is an all around a good rifle.

PRO: Multiple calibers and styles to fit the gun to the shooter, the weapon has high accuracy and is designed to last.

CON: Being a bolt action rifle the shooter may have to take their eye off the target to chamber the next round or to reload the 5 round flush magazine.


Knights Armament M110

The M110 is based off of the AR-10 and is a Semi Auto Sniper System (SASS). The rifle fires the .308/7.62NATO cartridge which has an effective range of 800 Meters.

PRO: The weapon is semi-auto letting the shooter acquire the target and keep an eye on the target after they fire the  weapon.

CON: The .308win does not have the range that some of the newer sniper rifles rounds have, such the .338 Lapua or The .408 Chey-Tac and .50 BMG.

Chey-Tac M200 .408 sniper rifle

The Chey-Tac M200 intervention fires the .408 Chey-Tac bullet. This rifle has set its mark in the sniper community as an anti-personnel as well as an anti-material weapon at long range because it has a better ballistics table than the .50 BMG

PRO: Can take out a target at well over 2000 Meters

CON: Same as the Remington 700 in that it is a bolt action.

FN P90

The FN P90 is a killer punch in a tiny package.

PRO: the weapon platform is small allowing for close quarters combat while still carrying upwards of 50 rounds.

CON: If you have a con for this weapon please share it with us.


The M14 is another time proven weapon. This weapon as been in service since 1957 and is still being made. the M14 fires the 7.62NATO round  allowing for the weapon to go from medium range out to long range sniping.

PRO: Semi-auto fire, 7.62NATO round,  800 Meters effective range.

CON: it weighs in at 11 pounds and is not a weapon you could easily use in CQB

H&K G36

Heckler-Koch G36  like the AR-platform lets the shooter customize the weapon to fit how the weapon will be used.

PRO: Reliable and accurate

CON: The weapon only fires the 5.56NATO round which is a small projectile and does not have the stopping power that a .30 caliber projectile has.



FN Herstal SCAR-H MK.17 is similar to the AR. FN makes a few different  versions of the SCAR but the SCAR-H is chambered in the .308/7.62NATO round which has the stopping power and range to take down targets at various ranges.

PRO: quick change barrel and heavy caliber

CON: If you have a con for this weapon please share it with us.


The AK-47 has been used by militaries the world over. The round is cheap and easy to find and has a better stopping power than the 5.56NATO.

PRO: the weapon works dirty filled with sand and water and keeps firing

CON: the weapon is not as accurate as an AR-15 or other similar weapons.

Ruger 10-22

We couldn’t talk rifles without talking about this .22 LR. this is one of the most well known .22s other there. it has been designed to do one thing and do it well and that is shoot .22s all day long.

PRO: cheap. fun to shoot, easy to find ammo and companies make lots of different stocks to let the user have many different looking guns from a G36 to an AR-15 to double barreled “machine” gun.

CON: If you have a con for this weapon please share it with us.

Noreen Bad News .338 Lapua ULR

Noreen Bad News .338 Lapua ULR


The Noreen Bad News .338 Lapua ULR (Ultra long Range) Rifle

This rifle is modeled after the AR platform however the take down pins are farther apart than the AR-10 and AR-15 rifles causing the rifle to not accept an interchangeable upper like the AR-15 and AR-10 platform. This rifle does use some AR parts like the pistol grip, stock and trigger allowing for them to be changed.

The magazine on this rifle comes in a 5 or 10 round proprietary magazine. One of our sources mentioned that a 50 round drum is in the works.

.338 Lapua magnum goes for about $70 per 20 rounds =3.50 per round.
.300 Winchester Magnum goes for about  $20 per box of 20 rounds = $1.00 per round.
.308/7.62NATO goes for about  $7 per round 0.35 per round.

The recoil felt has been compared to firing a .243Win. The rifles muzzle brake and semi-auto action significantly suppress recoil.

The weapon disassembles like the standard AR platform for easy cleaning. 

The manufacture of this rifle won a defense contract to make this rifle for military snipers.

Mk 14 Enhanced Battle Rifle

I unfortunately have been sick the past week and this is causing some problems with my keep up with the site and writing full informative posts but I am hopefully going to start feeling a bit better tomorrow and have a real post written for you.

Yesterday we reached our 100th post which I am very proud of but I was unable to write the planned posting for that day so we will celebrate tomorrow.

Chey-Tac M200 Intervention

Chey-Tac M200 Intervention


I saved my favorite for last.

Weight: 31 lb.
Length 53” (fully extended  stock)
Barrel length: 29’”
Chambered in: .408 Chey Tac
Action: Bolt
Effective range: 1500 – 2000+ Meters
Magazine: 7-round detachable box


This rifle has been made popular over the past few years from the video game Call of duty and movies like Shooter.

I first heard about this rifle in 2003 and the waves it was making in the ballistic world  with the new (at that point) .408 round and how it can remain supersonic at 2000 meters with the same kinetic energy (at 2000 meters) as a .44 magnum round shoot at point blank range.

Chey-Tac based the design off of the EDM Arms Windrunner .50 BMG sniper rifle in 2001. Rather than designing a rifle around an existing bullet they developed very-low-drag bullets with a new cartridge and then built the rifle to spec around the .408 Cheytac.


left to right: .50 BMG, .408 Chey-Tac, .338 Lapua , .300 Win Mag, 7.62 NATO and 5.56NATO.


Advantages of the .408 Chey-Tac
cartridge over the .50 BMG cartridge
• More compact
• 33% less weight
• Greater kinetic energy (beyond
400 yards)
• Shorter time to the target
• Greater velocity to the target
• Superior accuracy
• Engages targets at greater distances
• Remains supersonic longer for
greater accuracy
• Less primary recoil due to lighter
• Greater raw materials savings in


The Chey-Tac muzzle brake suppressor, manufactured by OPS INC, is a stainless steel suppressor. The all stainless steel construction with no replaceable parts guarantees a suppressor life that equals or exceeds the life of the rifle. When totally filled with water, the suppressor can be drained in 6 seconds which allows use when emerging from water. If the operator chooses to switch to the muzzle brake, a repeatable 6 minute of arc zero change for elevation is required.

I must say I do really like the .408 Cheytac round.

.408 Chey-Tac

.408 Chey-Tac


It would appear we are on yet another single weapon week.

This bullet was designed in 2001 by John Taylor and William O. Wordman.

This round was designed to bridge the gap between the .338 Lapua and the .50BMG  in performance. This round stays supersonic at well over 2000 meters and has the same kinetic energy at a at a mile as a .44 Magnum. (as stated by a Chey-Tac spokesperson)

(50 AP = .50BMG Armor piercing)

This round has the ballistic properties for anti-personnel, anti-sniper and anti-materiel roles.

In  the civilian market this round cost more than the .50BMG ($4 per round) and the .416 Barrett ($5 per round). the .408 is about $7 a round factory made.
