DSA AR15 M16 Cut Sand Cut Enhanced Bolt Carrier Group

The DS Arms ESC – Enhanced Sand Cut complete bolt carrier group is the pinnacle of AR15 – M16 bolt carrier group production. We took our standard Mil-Spec bolt carrier group and ungraded with real world no-nonsense features that make sense, not just make it flashy! First and foremost we looked to our roots in the FAL Battle Rifle and incorporated L1A1 style sand cuts on the entire load bearing surfaces of the carrier. These sand cuts allow any sand, dirt or debris that may have gotten into the action to easily be cycled out.

The DS Arms AR15 M16 Cut Complete Sand Cut Enhanced Bolt Carrier Group is perfect for your next build. We machine these assemblies using the latest manufacturing techniques, material and finishes. The carrier is shot peened 8620 Steel and the bolt is MPI 9310 material. The interior of the gas key & bolt location on the carrier is chrome lined per Mil-Specs. This complete AR15 M16 cut bolt carrier group assembly includes the complete bolt, complete carrier with properly staked gas key, cam pin, firing pin and firing pin retaining pin.

How do I tell the difference between a Metric and Inch pattern?

– L1A1 Barrel profile at the breech has a longer taper.

– On the Metric the gas block ears are closed on both. The L1A1 Gas block ears are open on each side & front sight post has a set screw at the face of the gas block.
– Magazine tooth on the L1A1 inch pattern is a much larger squared protruding lip. The metric has a small radius protrusion. The corresponding relief in upper receiver will be cut as a deep channel on the L1A1 all the way across the inside of the engagement surface. The Metric upper receiver will have a small semicircular notch in this area that will match the protrusion on the Metric magazine.
– The L1A1 Lower receiver has extensions where the buttstock meets the back face of the lower/trigger housing. These extensions have a radius as they form into the buttstock tang. On the metric the back edge is straight vertical line. Also on the L1A1 the trigger plunger assembly is housed in the pistol grip. On the metric rifle the trigger plunger is mount on protrusions on the bottom of the lower. The internals are also different and not interchangeable.
– L1A1 Bolt hold open shaft is slightly larger than metric shaft. A metric bolt hold ope will fit in a L1A1 receiver but the L1A1 will not fit in a metric receiver.

– L1A1 charging handle slide bar is slightly thicker than the metric version. L1A1 can be shaved down to fit a metric receiver. The L1A1 charging handle requires the receiver to be cut in order to engage the folding lever and lock it in the forward position.

– Bolt & bolt carrier will interchange as complete assemblies however extractors and firing pins do not interchange.

– Muzzle end barrel threads are 9/16×24 TPI right hand on the L1A1 but left hand on most metric versions. Some Belgian rifles can be found with either or. Early Belgian rifle can be right hand.

– Top covers on the L1A1 have 2 protruding ears on the bottom rear that fit into recesses milled into the upper receiver. Metric top covers do not have these ears.
– The above does not list all the differences but does cover the major ones. For more, please refer to the FAL Rifle Book by Blake Stevens.

What is the difference between receiver types?

They are basically the same, the only difference is cosmetic. Type 1 comes with and without a cut for a carry handle. Type 2 comes only with cut for carry handle and it has different lighting cuts on the rear left and right side that radius in and out.
 
The type 1 came first in the 1950’s and early 60’s then the type 2 started in the 1960’s. This is a personal preference choice and can been seen on the photos posted on our site or in the FAL Rifle Book.

How can I order a rifle or receiver from DS Arms?

AFTER placing your order please send over or have your dealer send over a copy of the transfer FFL to either FFL@dsarms.com or fax to 847-277-7259. You must include your order number when providing a FFL. Should you have any problems please call us at 847-277-7258. If your dealer needs us to reach out to them to get a copy of their FFL we will happily do so; you as the customer just need to let us know who to contact. All serialized items must ship to a licensed FFL dealer for appropriate transfer paperwork to be completed.

What is the lead time on rifles?

In general the production lead time for complete rifles is approximately 4 to 8 weeks from date of order. Obviously depending on outside market factors this can change substantially.

What is our backorder policy?

If you have a backorder item it will be indicated on the invoice with the letters BO. We do not charge for any backorders until that are filled and ready to ship.

Do rifles take inch or metric magazines?

Our rifles take metric magazines and are fabricated using the original metric blueprints.

Do I get a tracking number with my order?

After the order is invoiced and packed you are automatically emailed a tracking # to the email you provided at the time of the order

Should I use .308 win ammo or 7.62 nato in my FAL?

Due to our chambers and the action of the FAL it is safe to shoot both NATO Spec 7.62×51 and Commercial .308 Winchester.

Generally, we recommend trying to stick with the 7.62 NATO but shooting commercial .308 Winchester won’t harm the rifle. You will want to stay as close to the 147-grain weight projectile as possible.

We do not recommend the use of heavy or high-powered hunting rounds, ballistic/ soft tipped projectiles or any steel cased ammunition.

What kind of accuracy can I expect from my FAL?

Using a good commercial grade ammo with 147 gr FMJ bullets approx. average 3″ to 4″ at 100 yards. However, much greater accuracy has been achieved and reported by many customers including MOA. This depends on many variables that are too lengthy to list in this section.

How do I set the gas regulator on my FAL?

Refer to page 24 in the field manual (you can download page 24 & 25 from our web under “printable forms” tab) and remember, to capture more gas, turn the regulator toward the gas block, (clockwise or towards the right) when looking down from the top of the handguards. This will make the rifle extract and eject with more force. To release more gas, turn the regulator away from the gas block or towards the left. Keep in mind you want the rifle to eject positively yet have the regulator opened enough so as to cause less recoil and wear on its working parts. However it should not be opened so far as to cause a short cycle, this will differ depending on the differentloads and brands of ammunition.

This feature is unique to the FAL and one of the great advantages of the FAL system. So utilize it to your benefit. It enables the rifle to keep functioning with high round counts when other rifles will just fail due to being too full of carbon and debris.

Do we ship over seas?

All overseas order must be under $100.00 for parts and accessories. No barrels or bolts will be shipped until an approved export license is obtained from the State Department Office of Defense Trade Controls. This can take anywhere from 1 month to 9 months depending on their backlog and response time. Remember this is a Government agency and not in our control, don’t shoot the messenger as we do not dictate policy.

 

Hopefully changes in these cold war era policies will be forthcoming and positive.

 

If you have issues or complaints with these policies we suggest you contact the FAIR Trade Group at (202) 296-2537. Also contact the NRA ILA at (703) 267-1166.

If you would like us to apply for an export license for you on our products, a nonrefundable fee of $250.00 is required. This does not guarantee an approved license will be issued. We will also need a Purchase Order, a copy of your import license or in cases of government orders an official request on Government letterhead and in some cases a DSP-83 end-user certificate.

Rifle Option Compatibility

PICATINNY GAS BLOCKS AND LOWERS: Picatinny gas blocks and lower have to be used together and not separate to keep the sight plane correct. The picatinny set up is great if the user wants to co witness with an optic. The picatinny set up is also great if the rifle is a scoped only rifle and needs only back up irons sights or no iron sights at all. The picatinny set up is best applied with a full rail interface option. For this option the user would have to purchase an extended scope mount and the rail interface hand guards.

FORWARD ASSIST: The forward assist option was created by the Israeli’s so they could assist the action in closing. It works by pushing in and forward at the same time. The forward assist is not compatible with a Para FAL because of the sand cut carrier.

L1A1 FOLDING COCKING HANDLE: This option was developed by the Canadians and used on most Inch pattern (L1A1s) FAL rifles. It was only used a lot PARA FAL metric rifles. The L1A1 folding cocking handle can be used on most FAL rifles except rifles ordered with a free float hand guard.

MATCH TRIGGER SET TRIGGER: This trigger was developed by DS Arms and will give the rifle a 2.5-3 lb trigger pull. This trigger option uses a reduction button that is installed into a SAW grip (only). This is an excellent option for a FAL rifle that is going to be primarily used in a stable position, like off a bench or bi pod.

SPEED TRIGGER: This is custom gunsmithing work that is done to the fire control components. This work results in a very crisp, smooth 5.5 – 6 lb. trigger pull with very little take up and almost zero over-travel. This is accomplished by polishing, honing and mating the fire control components to each other.

What is Nitride treatment?

Nitriding is a process that has been utilized by many manufacturing fields for many years including firearms manufactures. Mil-Spec chrome lined barrels have a chrome lining that is .0003″ to .0005″ thick on top of the steel, while the Nitride hardens the material .005″ deep. Since chrome lining is plating process, it can chip and flake off as well as effect accuracy, where Nitride is a treatment that changes the barrel steel on a molecular level. This makes the steel “stronger/harder” by increasing the Rockwell hardness. Nitride also covers the inside and outside of the barrel, this is important as well because the Nitride process offers excellent corrosion resistance with a Rich deep black finish.
