The Firearm Blog

A while back I blogged about the, quite frankly, ugly bullpup kit by Centerfire Systems for the AK-47 that could be used with a Saiga-12. The Kushnapup is a much better looking system designed specifically for the Saiga-12 shotgun.

This video shows 10 slugs being fired from a Saiga fitted with the kit.

The kit does not require any permanent modification to the shotgun and can be easily installed, no gunsmith required. The current model only accepts stick magazines, but a new kit is in development and it will accept drum magazines. The kit costs $275.

Shernic Gun Works have unveiled a new bullpup conversion stock for the SKS rifle.

Two things differentiate the stock from other attempts at SKS bullpup conversions. The first being that it can be loaded with stripper clips and the other being the low price of $159.95.

I am not entirely sure how it works, but from what I can see in the below video, the bolt dust cover / cheek rest, for lack of better terms, is spring loaded and can be popped open, either with a button or unlatching it somehow. When it is popped open and the bolt locked back a stripper clip can be inserted into the magazine. After loading, the cheek rest can be push closed. While it can be used with SKS rifles that take either AK-47 or Tapco magazines, many people, including myself, don’t like the magazine conversions and prefer the simplicity and robustness of Simonov’s original design.

The stock does not require any permanent modifications and the original front sight assembly can be left on the rifle, but it is not heigh enough to be of any use.

The stock will not be shipped before September, but it can be pre-ordered at a discounted rate. The manufacture will be sending me some more photos of the stock shortly.

When asked what “bullpup” I generally tell people “it is a rifle where the magazine sits behind the trigger”. Rabbityrabbit came up with an idea for a bullpup where the chamber is behind the trigger, but the magazine is in the same place as it is on a non-bullpup rifle. The design idea was inspired from the Boberg XR9 pistol.

While I think this idea could work well, many armed forces do fine with a standard configuration bullpup.

After being delayed a few time the Kel-Tec RFB .308 Bullpup is now shipping.

Kel-Tec:

We are happy to confirm that the RFB is in production and shipping to distributors (yes, it’s true!). We are currently shipping small batches, however full-scale production will commence in the coming weeks! On a similar note, we have purchased three (3) new CNC machines specifically for RFB production.

More info on the RFB.

I came across a Russian firm called DAC / Demyan who manufacture a bullpup conversion of their T-4 Carbine PCP bolt action rotary magazine repeating air gun.

T-4 Bullpup


T-4 Carbine

The conversion to a bullpup configuration is straight forward. Initially I was confused by what appears to be a double set trigger but after looking at the below diagram is seems to be a simple safety that prevents the trigger from moving.

If you have ever wondered how bullpup rifles work then take a look at this cutout. I have annotated the diagram so that it is comprehensible by those with less technical knowledge of firearms. The parts needed to move the trigger forward, the trigger linkage, are plain to see.

Another interesting feature of this rifle is the built in suppressor. This probably prevents it from being imported into the US and any another other country that regulates suppressors. The Gamo Whisper, which also includes a built in suppressor, is apparently legal because its’ suppressor is made from plastic and would be blown up by the gas from even a .22 LR cartridge.

The T-4 is available in .177, .22 and .25.

Specs:

Weight: 2.8 kg : 6.1 lbs
Length: 680 mm / 26.7″
Barrel length: 420 mm / 16.5″
Trigger pull: 1.5 kg / 4.4 lbs
Magazine Capacity: 8 pellets
Operating pressure: 30 MPa (300 bar)
Verification pressure: 45 MPa (450 bar)

Price (Carbine, bullpup price not listed): 40000 Rubles (currently US$ 1371.88).

The stock seems to have been through a variety of evolutions. These are other photos I found:

I prefer the P90 inspired stock, although the pistol grip looks a bit square.

A cursory google search did not reveal a US distributer. Demyan is going to be at SHOT Show 2009 so either they do have distributor lined up or are looking for one. The SHOT Show description of the company:

Original research and manufacture of sportguns. Our company produces high-quality air rifles for Fild Target, BenchRest, as well as compact powerful air rifles for hunting by caliber 4.5, 5.5, 6.35.

If you are going to SHOT and come across their booth I would be interested to know who their distributer is, if they have one, if the T-4 carbine is going to be exported to the US, and if so its’ price.

taofledermaus has published a video tutorial on how to fit a Ruger 10/22 receiver, trigger and barrel into a $30 airsoft P90 stock and how to hook up the airsoft trigger to the 10/22 trigger at the rear of the stock. A very clever idea.

Last month the Croatian Ministry of Defense unveiled the final design of the VHS assault rifle (Višenamjenska Hrvatska Strojnica – Multifunctional Croatian Machinegun). The rifle has been in development for many years by Croatian manufacturer HS Produkt who are better known for their HS 2000 pistol ( sold as the Springfield Armory XD in the US).

The first version of the rifle bore a striking resemblance to the Israeli Tavor and Singaporean SAR-21:

Early prototype

The early prototype rifle utilized an interesting gas system. Reading the patent and other info on the internet it seemed to be a new take on gas delayed blowback. A piston is used to push back the bolt and gas is piped behind the bolt to slow it down.

The new model bears more than a slight resemblance to the French FAMAS. The external design is without doubt inspired by the FAMAS.

French FAMAS (from Wikipedia)

The gas system was ditched and the final production model uses direct gas impingement, the same system as the M16/AR-15, unlike the earlier model or the FAMAS, which uses a lever-delayed blowback action.

The rifle will come in two models. The 20″ barreled rifle model called the VHS-D (pictured above,) the 16″ carbine model called the VHS-K (pictured below). The VHS is chambered in the 5.56×45mm NATO and takes STANAG (AR-15) magazines. The price is estimated to be €1000.

According to Wikipedia the rifle will undergo trials in earyl 2009 and by 2012 60,000 will be in service with the Croatian army.

VHS-K prototype. Very compact!

Guns.ru has more info on the rifle.

I read about Short Rifle Stock Systems (SRSS) new M14/M1A bullpup stock, the BullDog 762, at Defense Review. I suppose the designers said to themselves “just about about everything has a bullpup conversion, why not the M14?”

The stock comes in a synthetic model (SRSS-1421SM, $749) and an aluminum model (SRSS-1421BA, $999) and is available in Black, Olive Drab, Tan and Aluminum finish.

From the FAQ:

What does the SRSS kit consist of?

The SRSS stock system comes with main beam (stock) panels = Cheek rest and right panel, optics rail and all hardware, allen wrenches to mount scope rail which replaces the M14 /M1A hand guard. Simple tools like a screwdriver is all you need to install your M1A or the M-14 into the SRSS. OPTICS are not included. See our site for Optics available.

Do I need to machine any part of my rifle?

No. You will need to remove the hand guard and install the optics rail and you will need to remove the rear sight assembly, just hang on to it you may want to put it all back together or leave the SRSS together and build another M1A.

Can you describe the trigger action ? I understand that one of the weakness of bullpup stocks is their softness or lack of tactile feedback of the trigger when pulled.

Our trigger was designed to eliminate all the problems that bullpup’s have. The trigger/transfer rod is submerged in the stock and to some degree floats and is carried by the rear/original trigger. The safety is just above the pistol grip for your right hand and can be turned off and on by the right thumb. Our trigger rod adds 1/2 pound to whatever your trigger pressure is on your rifle. It feels like your original two stage trigger.

Later this year or next year SRSS will be offering this stock system for other rifles. My guess is that a Mini-14 model will be offered.

Fitted with the SRSS Mini Paladin Muzzle Brake ($200)

UPDATE: Daniel E. Watters, who is very knowledgeable, points out in the comments that there have been other bullpup stocks for the M14.

Also on display at MSPO 2008 were the Alex bullpup bolt action rifles. They look awesome. As far as I know they come in three models. The Alex762 (7.62×51mm), Alex -338 (8.6×70mm / .338 Magnum Lapua) and the Alex Sports Tactical (7.62×51mm).

Very compact

It is so pretty I could not help posting another photo

The Alex-338 weights 6.5 kg without scope and 7.3 kg with the scope, 0.4 kg more than the Alex-762. It has a 5 round magazine. I can’t read Polish and I am unable to find more useful information on the rifles.

Earlier this year US firm Desert Tactical Arms launched a bolt action bullpup rifle at SHOT.

More information here, here and here.

I have done my best to find accurate information about this firearm on the Polish MSPO 2008 website. I do not speak or read Polish so I had to rely on Google Translate. If I got something wrong, please correct me in the comments.

CenterFire Systems sell a Bullpup stock kit for AKs:

Very cool.

Those lucky Canadians will be able to purchase the Norinco Type 97 later this year.

Type 97A. Click to expand.

The Type 97 is the civilian export version of the QBZ-97 rifle, which in turn is the export version of the 5.8×42mm QBZ-95. It is chambered in 5.56×45mm and takes STANAG magazines. Looking at the photo I think it has a 20″ barrel.

According to CanadaAmmo it will be available in December 2008 and will sell for $849.00.

UPDATE: A couple of photos from Dennis. Thanks Dennis

The above photo shows Chinese UN peacekeepers performing during a medal ceremony in Lebanon. It is interesting to see how they hold the bullpup to use the bayonet.

Kel-Tec displayed their new RFB 7.62×51mm (.308) bullpup rifle at SHOT Show. SMGLee took some great photos.

With suppressor, nice!

Wikipedia has this to say about the rifle:

The Kel-Tec RFB High Efficiency Rifle (Rifle, Forward-ejection, Bullpup) is a gas-operated semi-automatic rifle with a tilting breechblock locking mechanism, manufactured by Kel-Tec Industries of Florida. It loads the 7.62×51mm NATO (.308 Winchester) cartridge and uses metric FAL magazines. The rifle uses a patented forward-ejection system via a tube placed over the barrel that ejects the spent case forwards, over the handguard of the rifle.

The rifle is a forward ejecting semi-automatic firearm chambered in 7.62 mm NATO (.308 Winchester), utilizing a short-stroke gas piston. To avoid the sloppy trigger pull typical of bullpup style firearms, the RFB utilizes a floating linkage bar between the sear and the hammer, allowing the sear to remain above the trigger. The weapon is fully ambidextrous, much in the style of the French FAMAS bullpup assault rifle. The RFB accepts FN FAL style magazines, and is delivered without iron sights. A mil-spec Picatinny rail is standard.

Here is a video of the rifle, clearly showing the forward ejection.

Kel-Tec plans to offer three different four versions each with a different barrel length:

• Carbine (18″),
• Sporter (24″),
• Target (32″ heavy barrel, or 26″ stainless steel barrel)

The rifle is expected this quarter (1st quarter 2008) in the forth quarter, see the comments by dogon1013.

At SHOT Desert Tactical Arms announced their Stealth Recon Scout (DT SRS) sniper weapon system. It is a bolt action bullpup rifle.

It features

* 1/2 MOA accuracy is standard
* 11 inches shorter than conventional rifles
* Quick Caliber conversion between 243 win, 308 win, 300 win, and 338 LM
* Rugged, it was designed and built to be as tough as any other system out there.
* Adjustable trigger 1-5 lbs and you can also enable or disable the second stage on the trigger, as well you can reduce your trigger pull length to whatever you want.

The 338LM pictured below (with bipod, scope mount, sling, and S&B 5-25x) is 15.75 lbs and has an overall length of 37.5″. The 308 WIN (22″ fluted barrel) is approx 3 lbs lighter with an overall length of 31.5″, making it the shortest sniper rifle in the world to my knowledge, yet you can still mount the bipod the same distance forward on the rifle that you can on a standard McMillan stock.

We actually beefed up the barrel and bolt camming area up by 39% over the original DSR-1. Every operational sniper that has handled the rifles have said they are the most comfortable rifles they have ever handled.

The trigger is excellent, I can assure everyone of that and those going to the shot show will get to try it.

Postal, your hilarious, no black eyes with this gun. The bolt has a 60 degree lift and six lugs. The bolt manipulation is about 2-3 inches rearward of a normal bolt gun, It feels very natural and you don’t loose your cheek weld during operation. Your technique changes slightly but it is very accommodating. If you shoot the SRS left handed then you have to roll your head over slightly to manipulate the bolt.

We won’t be making a lefty, at least not for a while, sorry.
