Welcome to the ultimate Straight Pull AR15.
Manufactured by Lantac USA in Fort Worth Texas, the LA-N15 Straight Pull Raven™ features cutting edge design and functionality that pushes the limits of the AR to new heights.
We do not convert existing semi auto AR parts or purchase cheap US parts and assemble them in the UK. We do not use counterfeit or airsoft parts of any kind.
Our rifles are specifically designed by us and manufactured by us to be UK legal Straight Pull ARs. These rifles features precision machined components manufactured from the highest quality certified materials and finished using the correct military specifications for coatings and processes.
All small parts are sourced from military contract suppliers, feature NSN numbering and are manufactured to the latest specifications and revisions, so they are of the highest quality and reliability.
The Ravens CP-R360™ Domed Head Cam Pin reduces friction and wear to the upper receiver and creates a much smoother operation of the working parts. It is Swiss precision turned from 17-4PH (Precipitation Hardened) Stainless Steel and heat treated to H900 condition. A noticeable improvement to function can be identified.
The LA-N15 Straight Pull Raven™ features a completely dedicated, specially designed BCG (Bolt Carrier Group). The bolt is spring assisted and utilises our CP-R360 Domed Head Cam Pin for ultra smooth unlocking operation. Unlike converted carriers, Lantacs dedicated system is threaded for a handle prior to heat treatment so that the carrier retains strength and wear resistance in this important area.
Lantac's Straight Pull E-BCG® (Enhanced Bolt Carrier Group) is a patented design that uses completely milspec, tried and tested quality materials. The carrier is precision machined from 8620 steel that is heat treated to a 15N Rockwell hardness of 89.5-91.0. Critical diameters are hard turned/ ground so that perfect dimensions are maintained. The E-BCG® features a Carpenter 158 Bolt that again is hard turned after treatment.
It is S110 shot peened and 15N Rockwell heat treated to 89-90.5 hardness.
All bolts are MPI (Magnetic Particle Inspected) for defects prior to coating and all parts are QPQ (Quench Polish Quench) Nitrided to AMS2753B standards, for improved corrosion resistance and lifespan.
Lantac's BCG's have undergone Defense Standards (DEFSTAN 00-035) 72hr Salt Fog trials and surpassed the requirement with minimum corrosion evident on both the carrier & bolt, as compared to the standard MIL-DTL-16232G Manganese Phosphated BCG's.
Semi Auto 65,000 round count bolts have undergone MPI (Magnetic Particle Inspection),
Radiography & Microscope analysis that revealed only minor surface crack initiation to the lugs, while standard M4 bolts usually fail at circa 12,000 rounds with crack initiation and propagation causing the lug to fail on either side of the extractor recess.
Straight Pull shooters can rest assured our parts are of the highest quality and reliability.
The Straight Pull E-BCG® has been completely redesigned from a standard BCG and features a dedicated carrier intended for use solely in Straight Pull ARs. A lubrication port is machined into the side of the carrier so that oil or grease can be applied with the carrier and bolt in battery. The port aligns perfectly with a lubrication reservoir on the tail of the bolt, allowing the user to lubricate the mechanism without having to disassemble the rifle system.
The carriers alignment guide is lightened and the tail of the carrier is flared for improved concentricity and alignment within the upper receiver, this in turn improves accuracy and has been independently tested and confirmed by the US DoD.
Charging handles can be swapped out at will and together with three grip styles a short handle base is also included. This gives the shooter up to six different handle configuration options to choose from, at no additional cost.
Mounting of the side charging arm is achieved with the use of a 1/4 X 28 Tpi, Grade 8 fastener and a recessed mounting slot is machined into the carrier that offers a flat and secure surface. Additionally an index pin on the bottom of the handle prevents rotation of the arm and works with the screw to form an extremely robust assembly.
While our Patented charging handle designs have been sadly (and badly) copied in the past our customers can rest assured they are purchasing not only the best looking system on the market but the most ergonomic & flexible too.

Stubby Handle Base
A completely modular charging handle system comes as standard and offers the shooter the flexibility of either a knurled, neoprene or original steel and rubber grip design. Handles are precision Swiss turned and QPQ Nitrided. Arms are machined from 316 Stainless Steel, handles are then TIG welded in place and dressed.
