  A customer brought in a Remington 1100 Trap 12 gauge shotgun, and the used barrel they purchased on eBay wouldn't fit. The puzzling part is that the barrel fits on their brother-in-law's Remington 1100, and conversely, the brother-in-law's barrel fits on the customer's shotgun. Figure 1: Misalignment gap at the top of the open chamber.    Figure 2: Back of the barrel hitting the right side of the receiver. We quickly determined that the alignment groove in the newly acquired barrel was narrower than that of the factory barrel. This discrepancy caused a misalignment with the receiver, making the barrel tilt to the right and causing the right side of the chamber to hit the outside of the receiver. Figure 3: Barrel alignment groove. After determining the direction and amount of metal to remove, approximately 2mm, we used our gunsmithing precision files to carefully and gradually file away the excess metal in the alignment groove. This process requires patience, as you mu...

  This is our latest creation for our good friend call-sign Methos. His requirements were to build a custom long-range rifle on our AR-15 platforms. Luckily an unnamed DOD unit had already made the same request and Hornady answered the call with the 6mm ARC (Advanced Rifle Cartridge). This build features our custom 3.25 lbs trigger job with minimal pre-travel and a crisp clean break out of a stainless still trigger and hammer set. Polished to a mirror finish. We use stainless steel to prevent damage caused by removing the hardening coating on normal Mil-spec trigger and hammer sets. Another unique feature is the stainless-steel tanker-style muzzle brake that looks similar to the Barret .50 cal rifles. This matches the barrel perfectly.

  This is truly a one-of-a-kind build. Featuring the Bear Creak Arsenal’s patented right-side charging upper, Adams Arms carbine piston kit, and Frog Arms custom lower. This build required carbide bits to drill and tap the holes in the side of the Adams Arms bolt carrier using a template based on the Bear Creek direct-impingement bolt carrier. This transformed the Adams Arms bolt carrier into a right-side charging bolt carrier for this custom upper. Adams Arms piston is installed with their 15-inch M-Lok rail and barrel nut (the Adams Arms piston does not work with the Bear Creek barrel nut). In defense of Adams Arms, their piston kits were originally designed for mil-spec barrel nuts. Adams Arms are great pistons and I have a couple in my personal collection. Compatibility with more manufacturers’ barrel nuts is one of the reasons Frog Arms is now using Superlative Arms piston Kits.

Standard build with Del-Ton upper. The latest builds are with Bear Creak Arsenal uppers: California-compliant variant with fixed non-thumb through stock, fixed ten-round magazine, and no muzzle device: Bear Creek Arsenal .224 Valkyrie upper variant for long-range target or varmint hunting: All of these rifles feature Frog Arms trigger jobs.

Latest custom builds from Frog Arms using Superlative Arms piston kits. These pistons have adjustable gas blocks and their patented “bleed off” mode that allows proper cycling of the bolt carrier group. These pistons can also be used in restrictive mode, so the shooter can adjust manually to fit conditions. Below are the carbine and pistol length systems.

Tisa Duty 1911  Performed a trigger job and polished the sear. Produced a clean, crisp break at 3lbs trigger pull with additional internal polishing, spring replacement, and tuning.

Competition Only Glock 19 Polished internals and installed a Timney trigger. After setting pre-travel and over-travel, it produced a 2lbs trigger pull.  Note: This low of a trigger pull should never be used in duty or concealed carry.

Ruger Mini-30 Polished all parts and replaced trigger spring with M*Carbo kit. This reduced trigger pull from the factory 6-lbs to a safe 2-lbs which the customer loved.

AR-15 Adam Arms Carbine piston and Samson Evolution® Series handguard  The handguard is specially designed to accommodate pistons under the top rail.    

Advantage Tactical Sights installed on Glock 20  These sights have been installed on Glocks, Smith & Wesson M&P, Springfield Armory XD-S, and more. Other brands of pistol and rifle custom sights can be installed.

M1A1 Stock Refinishing With Tru-Oil.  The original finish was stripped to bare wood. All dents and discolorations were removed, and a light walnut stain was applied to restore to the original color. Tru-Oil produced a rich gloss finish. It can also be tailored to a satin finish if the owner would prefer.  

DuraCoat 1959 bolt action shotgun restoration (bottom) using bluing-colored DuraCoat and tongue seed oil on the stock. Remington 1100 (top) was also coated with a bluing-colored DuraCoat.

DuraCoat on a Springfield Armory 1911 Coated with flat black DuraCoat on the slide and light grey on the frame. Additional internal parts swap includes Wilson Combat trigger, hammer, sear, disconnect, and sear spring. Externally, we changed the beaver tail grip safety and added Pachmayr wrap-around grips.

  Custom AR-15 Carbine  Stag Arms lower with S&W M&P upper, Adam Arms piston, Magpul pistol grip, and extending stock. The fire control group was replaced with Franklin Armory's BFSIII-ARc1 binary trigger. This build also included an ambidextrous selector and Magpul's BAD Lever extended bolt catch.
