The TM-15 is precision machined from a 7075 T6 Aluminium forging while still including many features that are generally only found on higher end billet receivers.

All receivers are precision machined on state of the art CNC equipment which giving us the highest tolerances in the industry.  Each receiver is hand finished and hand inspected for a uniform finish that is unmatched by traditional mass production finishing processes.


The Military Specification hard coat anodized Per MIL-A-8625 Type III Class 2 spec with a 7 step quality control process. Each receiver is then coated by a commercial Teflon coating for further environment protection. 

Lower Parts Kit

The lower parts are made by various military contractors, for example the fire control parts, mag catch, detents, and pins are made by the same contractors that Colt use.  Bolt catches and selectors are made by the same contractor that supplies BM.  They are made to military specs other than the AR dimensions ( not M-16 ) on the fire control parts.  The fire control parts for the M-16 rifle come from the same manufacturer as made for the M-16 rifle.  Everything is first rate parts, not seconds, and made in the U.S.A.

Who makes the best receiver? Which receiver is the best? Which receiver is the highest quality?
Of course the answer is that all of them are pretty much the same. The actual brand of receiver means little to nothing. When deciding on which receiver you should purchase you should take into consideration two factors. Price and manufacturer. Of course if price is not an object, get the receiver that has the logo or emblem that you want. I know that is superficial, but the best receiver really boils down to the one you like the best.
There are currently FOUR Major manufacturers that produce the majority of lower receivers for the AR market. MMS, CMT, LMT and LAR receive orders from many licensed manufacturers who obtain an ATF variance to have them cut and logo receivers on their behalf.
Mega, Stag (CMT), LAR and Barrett (LMT):

Currently we sell Lower receivers from LAR ( Double Star )who makes them for:

LAR = Grizzly, Bushmaster (L Prefix), Ameetech, (?)DPMS, CMMG, Double Star, Fulton, Spike's Tactical, Noveske (new)


We use either ER Shaw or Wilson Barrels depending on the configuration, length, and Chrome lining.


We use a couple of different contractors for uppers, one contractor also supplies FN, the other also supply BM, DPMS, CD and a few others.  These are machined and finished to mil-specs.


Our handguard manufacturer supplies the majority of the manufacturers of AR’s with CAR and M-4 handguards in the U.S.

Why shouldn’t I buy a cheaper kit from one of your competitors?
A: We use forged front sight base (not cast), A-2 sight post (not A-1), sling swivel rivet (not
roll pin), heat shields in hand guards (A-2 and CAR), Military contract upper, A-2 grip, carrier
assembly, buttstock assembly and charging handle. The kits include Colt® contract fire
control parts, delta ring, gas tube, and buffer. We use 1x9 twist, chrome moly match Hbar
for our rifle kits and stainless 1 in 8” or 1 in 10” for our bull kits. We choose only the finest
materials and provide care down to the last detail of assembly. All of our kits are of the highest
level of quality and we proudly guarantee every one sold.

What do the kits include?

All Kits include:

Barrels, Gas system components ( gas tube, roll pin and gas


Magnaflux Info:

Magnafluxing, developed originally by Carl E. Betz, is a method of testing ferrous metals for surface and subsurface flaws. The component being tested must be made of a ferromagnetic material such as iron, nickel or cobalt, or some of their alloys. This test is often used on industrial tools, and engine parts during maintenance inspections. It can also be used to diagnose failure, as in crash investigations.

It works by applying a magnetic field to the component under test, using e.g. a permanent magnet. This will cause a high concentration of magnetic flux at surface cracks, which can be made visible by dusting iron powder or a similar magnetic material over the component.

Parts can be tested using one of two methods. The wet method consist of bathing the parts in a solution containing iron oxide particles. The wetted part is then placed in a magnetic field and inspected using a black light (ultraviolet light). The iron oxide particles are attracted to surface discontinuities or cracks, where the magnetic field is discontinuous. The particles flux around the imperfections and the patterns are visible under the black light.

The dry method is based on the same principle. Parts are dusted with iron oxide particles and charged using a yoke. The particles are attracted to the discontinuities and are visible by black light.

Magnetic Particle Inspection info:

Magnetic particle inspection processes are non-destructive methods for the detection of defects in ferrous materials. They make use of an externally applied magnetic field or half-wave DC (rectified AC) current through the material, and the principle that the magnetic susceptibility of a defect is markedly poorer (the magnetic resistance is greater) than that of the surrounding material.

The presence of a surface or near surface flaw (void) in the material causes distortion in the magnetic flux through it, which in turn causes leakage of the magnetic fields at the flaw. This deformation of the magnetic field is not limited to the immediate locality of the defect but extends for a considerable distance; even through the surface and into the air if the magnetism is intense enough. Thus the size of the distortion is much larger than that of the defect and is made visible at the surface of the part by means of the tiny particles that are attracted to the leakage fields.

The most common method of magnetic particle inspection uses finely divided iron or magnetic iron oxide particles, held in suspension in a suitable liquid (often kerosene). This fluid is referred to as carrier. The particles are often colored and usually coated with fluorescent dyes that are made visible with a hand-held ultraviolet (UV) light. The suspension is sprayed or painted over the magnetized specimen during magnetization with a direct current or with an electromagnet, to localize areas where the magnetic field has protruded from the surface. The magnetic particles are attracted by the surface field in the area of the defect and hold on to the edges of the defect to reveal it as a build up of particles.
