Jk Jk155Ltec30 155 Lt Flsh Reducer End Cap 30
The JK Armament 155 LT Flash reducer end cap in 30 caliber is a compact muzzle device built to tame muzzle flash while keeping your rifle's profile lean. Whether you're running a suppressed or unsuppressed 30-caliber setup, this aluminum end cap screws onto your barrel to reduce the bright flash signature that gives away your position on the range or in the field. The hard anodized finish stands up to repeated use and the elements, making it a solid choice for shooters who want flash reduction without bulk.
The 155 LT is part of JK Armament's LT (lightweight) line, engineered for shooters who care about saving ounces without sacrificing durability. Its compact design means you don't gain much length or weight, so it works well on hunting rifles, precision builds, or any 30-caliber platform where barrel real estate is at a premium. The hard anodized aluminum construction is reliable and proven in the field.
This end cap threads directly onto your 30-caliber barrel, so compatibility depends on your barrel's threading. If you're building a custom rifle, working with a gunsmith, or replacing a worn muzzle device, the 155 LT fits the bill. Pair it with a quality suppressor, or run it solo to knock down muzzle blast and flash during strings of fire.

Frequently Asked Questions
What barrel thread pitch does the 155 LT end cap fit?
This end cap is designed for 30-caliber barrels, but you'll need to confirm your specific barrel's thread pitch (commonly 5/8-24 or 1/2-28 for .308 and smaller cartridges). Check your barrel specs or consult with your gunsmith before purchasing to ensure proper fit.
Can I use this end cap with a suppressor?
Yes, the 155 LT end cap can be used on suppressed or unsuppressed rifles. Many shooters use it as part of their overall muzzle setup, though specific compatibility with individual suppressors depends on your suppressor's design and how your barrel is threaded.
Will this reduce muzzle flash noticeably?
The 155 LT is designed to reduce flash signature, though the degree of reduction depends on your ammunition, powder burn rate, and overall system setup. Unsuppressed, you'll see measurable improvement; when paired with a suppressor, the flash reduction is more substantial.
