To create a full-length top rail we chose VLTOR’s CVAS-14 upper handguard assembly ($325.95). It features a one-piece, extended-length top rail that runs from the gas cylinder all the way back over the receiver. It is secured at the rear by the dovetail for the rifle’s stripper clip guide; in the middle at the rear of the barrel; and forward at the operating rod guide—a super-rugged mounting system that permits the barrel to free float over the majority of its length. Machined from aerospace-grade aluminum, the CVAS-14 is vented along both sides, and includes three side flats with threaded holes for mounting optional 5-inch Pictatinny rail sections. Even though our vision for the finished rifle was a flat dark earth treatment, we ordered all the VLTOR components in black as we wanted to see how well the various ROBAR metal and plastic finishes we had in mind would match.
We packed up the M1A Scout Squad and all the VLTOR stuff and shipped it off to ROBAR to have them work their magic. We also included a staff-owned Aimpoint Comp M2 red-dot optic and a pair of rings to have them finished to match the rifle. ROBAR offers a wide variety of finish materials and processes for steel, aluminum and polymer gun parts, all of which offer distinct benefits.
Poly-T2 is a Teflon-based, modified epoxy coating designed to provide lubricity and corrosion protection for metal components exposed to harsh conditions. It provides corrosion protection in excess 1,000 hours of salt-spray exposure that exceeds the ASTM-B-117 standard. This ultimate protective finish is available in four colors: black, tan, dark OD green and gunmetal gray. We chose tan—a perfect match for most flat-dark-earth components—and had this finish applied to our project gun’s barrel and receiver, the VLTOR CVAS-14 upper handguard assembly, stock adapter and optic mounting rings.
NP3 is a satin-silver colored, electroless nickel-based finish for steel, stainless steel and aluminum alloys that co-deposits sub-micron particles of Teflon with electroless nickel. It permits firing a lot more rounds between cleanings, as powder residue has no wet or oily surface to cling to. NP3 is also very corrosion resistant, and its high lubricity and low co-efficient of friction greatly increase the life of high-wear components. It’s the perfect finish for load-bearing and moving parts, and carries a lifetime warranty. ROBAR coated our project gun’s bolt, bolt release, operating rod, gas cylinder, muzzle brake, hammer and internal components, trigger, trigger guard, safety lever, magazine latch and guide with NP3 (all of which previously showed finish wear and/or rust). They also NP3 coated all of the metal mounting and operating hardware on the VLTOR upper handguard assembly, buttstock and fore-stock, including the receiver extension tube. The cost for all of the Poly-T2 and NP3 finishing described above was $580.
Polymax is a spray-on finish that does not need to be baked like Poly-T2 does. It comes in the same colors as Poly-T2, and is the finish of choice for both polymer parts and metal components that cannot be baked, like optics. ROBAR finished the VLTOR fore-stock, buttstock, pistol grip and Aimpoint Comp M2 in tan Polymax, all of which are an excellent match for the metal components finished in Poly-T2. Total cost for Polymax finishing: $230.
Before finishing the VLTOR fore-stock and pistol grip with Polymax, we had ROBAR apply their non-slip texturing to the entire pistol grip and the sides and underside of the fore-stock ($135). This spray-on application is textured before it hardens, and becomes a seamless and permanent addition to the polymer components. (We also had ROBAR apply the same non-slip texturing to the Springfield Armory factory stock).
As usual, we were very pleased with our overall experience with ROBAR. The quality of all the finishing work was flawless, turnaround time and cost were both very reasonable, especially considering the amount of disassembly and reassembly time involved to detail all of the small parts and components. Not counting the texturing and finishing of the Springfield Armory factory stock and upper handguard, the total cost for all of ROBAR’s work on our project gun came to $945.
