No doubt, the .45 ACP will go down in history as the favorite cartridge among American servicemen for the last century. It has proven very effective in combat, unfortunately, firing one is not very easy on the ears. Do you love running your .45 ACP carbine or SBR through its paces at the range, but would like to make the experience easier on everyone's hearing? Aside from a licensed suppressor, the only answer is to add a legal muzzle device from Kaw Valley Precision.

Wear A 45 Extra-Long

This KVP .45 ACP XL linear compensator is 4.25 inches long from stem to stern. That gives you an expansion chamber that is twice the length of the standard version. This means that your mild-mannered Kaw Valley .45 ACP XL linear comp is working twice as hard to direct the muzzle blast downrange away from your face and ears. Your lightweight, maneuverable gun is kept that way because KVP machines this XL liner comp compensator out of super-tough aluminum. This keeps the weight down and the performance up where you want it.

If Looks Could Kill

I know, your little .45 SBR or pistol looks pretty wicked. However, the key word here is “little”. Compact is good, especially when it comes to a PDW, but what you don't want is to get your support hand in front of the muzzle, even by accident. With the added length of the Kaw Valley .45 APC XL linear compensator leading way, you avoid that trip to the emergency room. This lets you run a longer Hand Guard so you have more real estate to hang onto. Whether you choose the full-size XL or the slim-line version, your weapon will bark less and bite harder.

    Now wether this puts the noise foward or not is debatable from all the testing done on various channels but I have them on all my 45 acp guns and it’s great for extending things out (I personally like 4-5 inch barrels but don’t want 4-5 inch Handguards). These folks have the lowest prices. Buy here w confidence

  • Very satisfied with my .45 ACP XL Linear Comp

    I recently purchased this compensator for use on a 5" barrel CMMG Banshee, chambered in .45 Auto. This is my wife's PDW for home defense and the addition of the linear compensator was worth every penny. In addition to ensuring she won't accidentally overrun the handstop and reach in front of the muzzle, when coupled with the Banshee's RDB system and an after market hydraulic buffer we added, this has made her gun the lightest recoiling and flattest shooting .45 PCC that either one of us has ever handled.
