Fourteen Inches -- Is an NFA Shotgun Worth the Effort?

In today’s world of tacticool and combat hype, is purchasing an NFA shotgun worth the time and money when you can buy a short barreled, pistol-grip firearm that is “not a shotgun” such as the Remington Model 870 TAC-14? I think the answer to this question is yes.

VCS 965 NFA Short Barreled Shotgun

I recently purchased a Vang Comp Systems (VCS) 965 Shotgun. The VCS 965 is a highly modified Remington 870 pump shotgun with a 14-inch ventilated rib barrel which makes it an NFA-regulated short-barreled shotgun (see more information on the National Firearms Act below).* The key difference from a regulatory perspective is the stock on the 965. The stock on the 965 makes it an NFA shotgun whereas the pistol grip on the TAC-14 means it is not a shotgun even though it fires 12-gauge shotgun shells. Confusing right? But that is the nature of firearms regulation in the U.S.

So why bother with an NFA shotgun if you can buy a TAC-14, a Mossberg Shockwave, or similar non-shotgun? The VCS 965 NFA shotgun is only 6-1/2 inches longer than the TAC-14; however, the stock makes a big difference in how it handles and shoots. Getting accurate hits with the 965 is no different than getting hits with a standard eighteen-inch shotgun. However, the 965 is much easier to maneuver in tight spaces such as a building or vehicle. I have some experience with the TAC-14 and similar firearms can attest that accurately shooting these firearms with a pistol grip requires a fair amount of upper body strength and proper technique. If you are an experienced shooter, getting your hits with these firearms is not impossible as Hickok45 demonstrated in a video of the TAC-14 (see link below).

So how does the shorter barrel perform? I did some testing to determine the difference in pattern between an 870 with an eighteen-inch barrel and the fourteen-inch 965 barrel. Both guns have the VCS port modifications and I used Federal Power-Shok 2-3/4" 8 Pellet 000 Buckshot ammunition for testing. I shot five shells from each gun at ten yards. The 870 with an eighteen-inch barrel patterned five inches and the 965 patterned 6-3/4 inches – a negligible 1-3/4-inch difference.

Is an NFA Shotgun Worth the Effort? I think so. The advantages that the shorter barrel and stock provide and the fact that the performance differences between the short barrels and a standard eighteen-inch is negligible makes it worth the effort to acquire an NFA SBS. All in all, I am pleased with the VCS 965’s performance and look forward to putting it through its paces during a shotgun match.

Additional Note: I have some anecdotal experience with 14-inch shotguns. In the early 1980’s, I was fortunate enough to have access to the State Department’s Diplomatic Security Service (DSS) firearms research at Quantico, Virginia. At that time, the DSS was trying to identify the shortest functional length of a shotgun barrel when firing the standard magnum 12-pellet 00 buckshot load. The DSS goal was to identify the buckshot load’s peak dwell versus velocity and cut the barrels to that length. Said another way, the DSS wanted to have the shortest possible barrel without losing any velocity. (Peak dwell defined as the instant the powder completes burning as the shot column is moving down the bore.)

DSS researchers determined that thirteen inches was the optimum dwell/velocity point and cut Remington 870 barrels to that length for testing. A problem immediately surfaced. When the peak dwell/velocity point was at the barrel muzzle, the barrels were splitting. It turned out that the muzzle was also the barrel’s weakest point on the shotguns of that era. However, barrels cut to fourteen inches worked just fine and did not split. I believe that the common fourteen inch standard we see today likely resulted from the DSS research. As an aside, the Vang Comp experts said that the optimum dwell/velocity point with modern powders is about eight inches.
