DPMS 3G1 AR-15 Rifle Review

Always wanted to have an AR-15 and now I have one. DPMS is a well know manufacturer of AR-15 rifles and I have chosen the one that will be awesome for dynamic shooting like 3-Gun or IPSC.

So, what makes it a good choice for a competitive shooter?


18 inch HBAR teflon coated stainless steel barrel is enough for all distances of practical shooting competitions.
What is HBAR barrel? It means Heavy Barrel or heavy profile barrel. Those barrels are heavier but better for competitive shooters.

Gas System Length

Rifle length gas system. Full length means softer recoil.


DPMS 3G1 hast twist 1:8. Barrel twist refers to the rifling in the barrel of the rifle. This means that bullet makes a full 360-degree rotation in 8 inches.


Forged 7075 T6 A3 Flattop. That means that receiver is strong and already has a rail where you can install optics, red dot sight or iron sights.

Muzzle Brake
DPMS Miculek Compensator installed and it does reduce felt recoil and muzzle rise. But I plan to change it for a better one.


JP Single Stage trigger is nice for a new shooter but can be replaced with better one after some use.

JP handguard system is nice but pretty heavy, plan to replace it with lightweight handguard.

Gas Block
Railed Gas Block is not adjustable and pretty heavy so I plan to replace it too.


Put about 5000 rounds throught it and it works perfectly on all distances up to 400 meters (437 yards). The barrel is extremely accurate.
