Morane-Saulnier M.S. 223
The Morane-Saulnier M.S. 223 was the fourth in a series of parasol wing fighters produced in response to a French requirement for a lightweight fighter, and only differed from the M.S. 222 by having a new undercarriage.
The entire series of aircraft was designed in response to an Air Ministry specification for a lightweight fighter, which was to have a good rate of climb, an endurance of 1hr 30mins at full throttle and be armed with two 7.7mm machine guns. It was to act as an interceptor, climbing rapidly to catch enemy bombers as they crossed the French border. Morane-Saulnier responded with the parasol wing M.S. 121, but this lacked engine power and failed to achieve the required rate of climb. The M.S. 221 had a more powerful engine but still lacked speed. The M.S. 222 was given a turbo-supercharged engine. It had an improved rate of climb, but its top speed remained stuck at 166mph.
The M.S. 223 made its maiden flight in 1930. It was almost identical to the M.S. 222, but had a new main undercarriage. The earlier aircraft all had cross-axle landing gear, while the M.S. 223 introduced a divided landing gear with oleo-pneumatic shock absorbers. This was introduced in an attempt to reduce drag and improve performance. Soon after the M.S. 223 made its maiden flight the entire 'Jockey' programme was cancelled, as none of the seven designs submitted by different manufacturers had proven to be satisfactory.
This didn’t end the development of the M.S.121 family. A somewhat larger M.S.224 followed in 1931, and entered service in modified form as the M.S. 225.

Rifle Review, Initial Impressions: DPMS A-15
We'd like to introduce our friend Mike, who brings Kit Up! this guest post. Now, you know how we link words for certain readers, like this: (grunts, sometimes)? It's for guys like him. We were as surprised as you will be by how articulate he is for a grunt, which is one of the reasons we used to go support single dancing moms with him. Please give him a read and extend a proper welcome. He is neither a hippie nor a sissy, nor has he ever gone so far into the cave to find his power animal that he failed to come back out.
Kit Up! A new California compliant A-15 from DPMS
The DPMS A-15: First Review
I recently purchased a DPMS A-15 in cal. 223 from a local gun shop in Northern California and took it to the range to break it in. These are my initial observations.
I originally went in looking for an AR from a different manufacturer [than DPMS], but unfortunately the one the store stocked in my price range didn’t have the features I wanted (a forward assist and an ejection port cover). My ultimate goal was to get an M4 military style rifle like the type I carried in Iraq the DPMS had those features and was affordable. I have to admit that I didn’t know much about DPMS rifles, aside from knowing an Army buddy who likes their lowers. After examining the rifle, including breaking it down and a function check, I filled out the paperwork, paid for my new weapon, and went home to wait the required 10 days. (Note: all photos courtesy of Boom Operator Ryan.)
The Rifle and First Impressions
My A-15 has a 16” chrome-moly barrel with a “cut out” for attaching an M203, a six position collapsible stock, and an A3 upper receiver with removable carrying handle and A2 style hand guards. DPMS coats its rifles with a Teflon hard finish and mine came from the factory and gun store without a scratch. The rifle came with its own case, albeit not a very durable one, and included a 10 round magazine, sling, a 25 meter zeroing target, the normal literature and a sticker. Awesome!
Now, as I reside in ‘The Peoples Republic of California,’ I have to adhere to certain firearms laws – specifically the 16” barrel length and the use of a tool to remove the magazine from the weapon (also called a ‘Bullet Button’). After having used an M16 series weapon with a normal magazine release for longer than some of the younger Soldiers in my unit have been alive, manipulating the California compliant DPMS involved a bit of a learning curve. The final constraint is the limit of 10 rounds in the magazine, but like the bullet button one can be dealt with.
So far the only modifications I’ve made are adding a Magpul MOE trigger guard and an ASAP sling adaptor. I may dress it up with a rail system, optics later. The rifle is well constructed, solid and feels good in my hands. Since it’s a brand new, it’s still tight, the edges are still ‘sharp’, but everything moves freely. It reminds me of when I had my brand new M4 issued to me.
I was looking forward to putting some rounds down range.
Range Going Hot
My friends Doc and Boom Operator Ryan planned conduct a zero range for my new rifle. However a storm was due to arrive on the designated day, and I scrambled to get everyone together before it began to snow. Doc was busy but Ryan was free, so we headed up the hill. It wasn’t as well-planned as we’d originally hoped, but we still managed to put a couple hundred rounds down range to get a feel for the weapon.
Once site, we set up a few gallon milk and juice jugs filled with water, paced off 25 meters, did a final weapons check and got down to shooting. All with a wall of dark grey clouds approaching from the west.
I fired from standing, kneeling, and prone supported and unsupported. At 25 meters, with battle site zero and no adjustments, the rifle fired a little low However after finding the point of aim I was popping milk jugs and splattered a large grapefruit left on the range in a spectacular manner [Note: in some places shooters prefer to engage old refrigerators and dishwashers dropped seemingly from the sky into the middle of nowhere – true story. We know. We’re from the MidSouth. Duo]
The recoil was smooth and there was no play between the upper and lower receiver that one occasionally finds in older used ARs. Trigger pull and reset felt the same as my issued weapon. After some slow careful shots to feel the weapon out I tried some ‘rapid’ fire to see if any cycling issues cropped up, and none did. The weapon fired 200+ rounds without a single malfunction – by no means a definitive stress test, but a good start. With storm clouds overhead, wind picking up and temperatures dropping, Ryan and I policed the range and called it a day.
To quote Emil Antonowsky from 1987s ‘Robocop,’ “I LIKE IT!” My DPMS A-15 is exactly what I was looking for in an AR platform and was the right price. I recommend it, and offer only two (correctible) cons if pressed: 1) the buffer tube is not MilSpec, and 2) there is a prominent ridge that encompasses the forward end of the rear stock that dug into my cheek when firing, This too can be replaced, but it would be nice if the lip wasn’t quite as aggressive.
Stay tuned as I’ll post a progress report with more tales from the range. And if you’re a DPMS user, I’d love to hear your thoughts.
The M4/M4A1 5.56mm Carbine is a lightweight, gas operated, air cooled, magazine fed, selective rate, shoulder fired weapon with a collapsible stock. It is now the standard issue firearm for most units in the U.S. military.
Equipped with a shorter barrel, collapsible stock and detachable carrying handle (with a built-in accessory rail) it provides soldiers operating in close quarters with improved handling and the capability to rapidly and accurately engage targets at extended range, day or night.
A shortened variant of the M16A2 rifle, the M4 carbine provides the individual soldier operating in close quarters the capability to engage targets at extended range with accurate, lethal fire. The M4-series Carbine achieves over 80% commonality with the M16A2 Rifle and replaces all M3 .45 caliber submachine guns, and selected M9 pistols and M16 rifles.
Want to know about the M4 Carbine? Here are a couple quick bullet point facts in this episode of "Bullet Points: M4 Carbine." Watch the video.
The Army is pursuing a two-phase PIP to keep the M4 carbine inventory strong. Phase I upgrades the Army’s M4s to the Special Forces’ M4A1, while Phase II explores future improvements for the M4A1 Carbine to deliver enhanced reliability, durability, ergonomics and zero retention.
There are several benefits to upgrading M4s to M4A1s. Compared to the M4 , the M4A1 has full auto capability, a consistent trigger pull, and a slightly heavier barrel. The heavier barrel is more durable and has greater capacity to maintain accuracy and zero while withstanding the heat produced by high volumes of fire. New and upgraded M4A1s will also receive ambidextrous fire control.
Project Manager Soldier Weapons (PM SW) initiated Phase I by modifying its contract for the production of M4s to the M4A1. PM SW took delivery of 9,582 new M4A1s to complete this action. In support, TACOM Life Cycle Management Command will have fielded approximately 6,000 M4A1 Carbines to the 101st Airborne Division by September and plans to field an additional 3,000 M4A1s to another unit within the next several months.
PM SW also held a competition for the manufacture of 24,000 additional M4A1 Carbines. The Army awarded a contract in April to Remington Arms Co. The award came under protest and the Army is currently developing several courses of action to comply with the Government Accountability Office ruling and concerns regarding the competition. Once the contract dispute is resolved, other services will be able to place M4A1 and M4 orders against the contract as well.
The main thrust of Phase I is to upgrade existing M4s to the M4A1 configuration. The Army authorized the conversion of all M4s to the M4A1 standard with the upgrade currently budgeted for 300,000 M4s. The Army will complete the upgrades through the purchase of components that support modification work orders (MWO) that will be applied by Small Arms Readiness and Evaluation Teams (SARET).
The Army awarded six contracts for MWO kit components to date. Five of the awarded contracts went to small businesses. The awards reflect a success in the Army’s strategy to broaden the opportunities for small arms contractors and strengthen the diversity of the industrial base. PM SW anticipates awarding the final contract this summer for the barrel and bolt assembly. SARET is scheduled to begin upgrading M4s at a maximum rate of 8,000 a month beginning in late summer 2013.
PM SW completed its best value M4 carbine bolt and bolt carrier assembly competition in April 2012, though the competition was scheduled to conclude in summer 2013. More than six months of testing and evaluation determined that none of the 11 competing designs met the overall requirements outlined in the solicitation. The M4’s current bolt and bolt carrier assembly outperforms the competing designs in the areas of reliability, durability, and high-temp/low-temp tests. The Army saved nearly $2 million as a result of the early completion of the competition.
The conclusion of the bolt competition, however, does not impact the search for a better forward rail assembly. PM SW completed bid sample testing for a forward rail assembly competition in early August. The Army may award contracts to up to three finalists in early 2013 with the selection of a final winner in early 2014. If the Army determines that the winning rail system should be procured, delivery of new rails is anticipated in the summer of 2014.
The M4 PIP is just another step in a long history of continuously improving Soldier weapons. The Army has already made more than 90 performance “Engineering Change Proposals” to the M4 carbine since its introduction. Improvements have been made to the trigger assembly, extractor spring, recoil buffer, barrel chamber, magazine and bolt, as well as ergonomic changes to allow Soldiers to tailor the system to meet their needs. Today’s M4 carbine is quite different “under the hood” than its predecessors and tomorrow’s M4A1 will be even further refined to provide Soldiers with an even more effective and reliable weapon system.
