These receivers are in short supply, and are temporarily discontinued while we shift our focus to manufacturing the parts to support the receiver for builds (Op Rod, Trigger Group, Bolt, etc…), it would behoove you to take advantage of this offering while they are still available.

SEI barrels are short chambered! SEI recommends that you send your rifle to us here for barrel installation – all our M14 barrels are short chambered, and require fitting to the receiver. We use a special-made Manson M118LR reamer, that allows accurate headspace for M118LR 175 gr. through M80 ball ammo.

Please also note that these barrels are provided “in the white” to our customers. If you request M80HT heat treating, the barrel must be headspaced by us prior to heat treatment.

SEI barrels are not hard chromed in the bore!

SEI will also parkerize your barrel for no extra charge. When you purchase online, please be sure to make this request in the comments box at the bottom of the online order form.

950 yard proof these barrels work... click here

This is a great replacement for Scout rifles, a Scout-type gun build, or MK14 Navy, M39EMR/USMC weapon. Very accurate out to 900+ yards with good grade of ammo such as M118LR or U.S.N. MK316 ammo.

The SEI P/N 2013 GLFS-D-18 gas lock, made from fatigue proof steel, has the correct deck height that allows the use of a standard USGI front sight, or one of our bar stock sights (shown below): P/N 2055 USGI replacement, P/N 2004 National Match with .062” blade, P/N 2018 Tritium Bar Stripe, or P/N2019 Tritium Dot.

Our barrels will shoot 1 MOA with M118LR or any of the 168 gr. factory match ammo. USGI LC M80 ball or any of the U.S. made M80 ball (with the exception of Portuguese 147grn. from the 1980’s) will shoot under 2 MOA most of the time.

We recommend that you use the P/N 2001V SOCOM Kit, The SEI gas lock, made from fatigue proof steel, has the correct deck height that allows the use of a standard USGI front sight, or one of our bar stock sights (shown below): P/N 2055 USGI replacement, P/N 2018 Tritium Bar Stripe, P/N2019 Tritium Dot, or P/N 2004 National Match. We also recommend replacement of the standard rear sight with P/N 2020, that uses a smaller aperture for better accuracy.

WARNING – Will not work with factory SOCOM or SOCOM II XS Style Front sights, they sit egregiously high and will have you shooting extremely low past the point of adjustment.

This part features a standard front sight deck height that allows the use of Standard GI Sight (P/N 2055), NM Front Sight (P/N 2004), Tritium Combat Bar Sight (P/N 2018), or the Tritium Combat Dot Sight (P/N 2019).

The SOCOM 16 factory muzzle brake is a one-piece casting that features a lower deck height than a standard M14/M1A. In order to compensate, sight that is sold on the SOCOM 16 is taller and wider, and the aperture is also wider, than the regular M14 version. The blade on the factory SOCOM XS sight is .135" and the rear aperture is .130”, compared to a front sight width of .075” and an aperture of .065” on a standard size.

Solid bar stock 1144 Fatigue-Proof steel with mil spec magnesium phosphate finish. Use of XF-7 Grease (pn #1019) on the muzzle threads during installation is recommended. Threaded 5/8x24 .735.

The dove tail deck will fit any USGI type front sight, including:
P/N 2055 SEI/USGI standard front sight
P/N 2004 NM .062
P/N 2018 Tritium Bar Stripe
P/N 2019 Tritium Dot

If you are using this with an 18 inch barrel:
18" barrels will shoot higher than 22" barrels. To compensate, SEI recommends P/N 2012 GLFS-D-18, or P/N 2013 GLFS-D-18 Gas Lock that is at the correct height, mated to a standard front sight such as the ones mentioned above. Springfield Armory uses a taller front sight like the Springfield Scout.

Please note: SEI parts, particularly those that are manufactured from solid bar stock, are produced in batches, so customers my experience some delays in availability.

Now, machined from bar stock and case hardened. Limited civilian availability. A must for high stress or cold weather applications. Standard issue on USN & USAF MK14's and US Army M14SE's.

Current design does not allow the bolt to close with an empty magazine inserted (but it can be closed if the magazine follower is pressed down).

CAUTION – the extended bolt stop/release is designed to make access and manipulation of the bolt much easier and faster. Therefore, DO NOT REST THE WEAPON ON ITS SIDE OR LEAVE IT UNATTENDED if the bolt is locked back and a loaded magazine is in the receiver. ALWAYS KEEP THE SAFETY ENGAGED.

The SBR (Smith Battle Rifle) Gas Piston has been developed for the demands of 21st century warfare, and is superior to the issue versions.

Made from 440c cutlery grade stainless steel and stress relieved. OD grooves are fully radiused on the bottom (instead of square) to enhance cleaning and carbon removal. After heat treatment and through hardening to 58 HRc Rockwell, the pieces are ground to final dimensions, with a glass-like surface finish of 9 on the Profolomater, machined to tolerances of +/- .0005” (1/2 of 1000th of an inch). Final finishing includes surface hard chrome plating to .0005” depth, and heat treatment to our SOP to prevent chrome cracking and hydrogen embrittlement.

Developed for war fighters with the M14,EBR,EMR, etc., made to resist corrosion and excessive wear, the corners stay sharp where needed to minimize gas blow-by. When used with our M80HT gas cylinder, wear is kept to a minimum, and can withstand infrequent maintenance in the field. Accuracy will not be diminished and may improve as long as the barrel is in good condition.
