r/GunPorn - Experimental semi-auto Springfield M1903 - Inventor unknown [1800x1026]
Experimental and possibly one of a kind semi-automatic rifle built on a Model 1903 Springfield Action. This rifle, serial no. 389864, is illustrated and briefly described on pages 6 and 7 of “THE GAS TRAP GARAND” by Billy Pyle. The caption describes this rifle as an “enigmatic M1903 conversion, inventor unknown. This rifle, which has a fixed barrel and no gas system, appears to be primer-actuated.” The rifle has a standard Model 1903 barrel, rear sight, upper and lower barrel bands, buttplate and front sight. The barrel and receiver have standard Model 1903 Springfield markings; the barrel is dated “1-10”. The bolt, receiver, trigger guard and stock have been extensively modified. The receiver has been extended by approximately six-inches to accommodate the modified bolt. A seven inch section of walnut has been added between the original Model 1903 buttstock and forearm to fit the extended receiver.

The trigger guard finial has been extended several inches. The stock and most of the rifle components are early Springfield Model 1903 pieces c. 1910. However the rifle has a post-WWI course checkered buttplate and flat faced rear sight windage knob which, as the Billy Pile description suggests, may indicate that the actual modification took place in the 1920s using a pre-WWI Model 1903 rifle. The bolt is polished bright and the receiver, trigger guard and other furniture has a professional commercial blue finish. The early style “S” stock has been refinished and has traces of the original circled “P” proofmark on the wrist and a small “S” on the forearm tip. The stock modifications are professionally done and are barely visible on initial inspection. The added section matches the butt and forearm very closely in grain and finish. This is a rare and unique rifle that appears to have been modified in the early 1920s as one of the first attempts to design a semi-automatic rifle to replace the bolt action Model 1903 Rifle.

Enlisted has the Winchester 30M and R the Pedersen and Garand, johnson all of which competed to be the battle rifle of the us replacing the original 1903 Springfield ironically. J.C white and this Springfield are among 8 rifles that competed to become the primary weapon of the us army. Only the Pedersen and the Garands prototype moved on to final selection. I would love to see this weapon as a br3 squad weapon. The most advanced of the 1903 family tree with many weapons including prototypes rifles and sniper rifles.

The Pedersen is a laser, shoots sweet, has a 40 round gay looking magazine, but the Dev’s neutered it’s hitting power (6.2) so much that I have four and use none in actual battles. It would be nice to actually see a 1903 semi auto that actually does some damage. :rofl:

It would also be cool to see Mosin’s self-loading rifle on the subject.

the springfield with pederson device shoots a pistol bullet, why is 6.2 not appropriate?

This might shock you but barrel length effects more than accuracy, a longer barrel allows more of the gunpowder to burn before it’s ejected from the end of the barrel, it won’t give it semi auto damage but a small bump is justified.

This might shock you, but the 1903 with pederson device fires a 7.65x20 bullet which is a very shitty and weak bullet that has half of the power of .45 ACP.

That doesn’t really help when you’re shooting the same bullets the Pederson device uses. No matter the barrel length those continue to be weak

I didn’t say it wasn’t appropriate, I said I didn’t use it because it’s power had been neutered to 6.2 and it had a gay looking magazine :smile:
