Omega Manufacturing Universal Fit Buffer Spring Endplate Castle Nut Kit - For Buffer Tube Mil & Com

Installed on an 18" barrel length upper with perfect results.

work fine, and you cant beat the price

the buffer spring kit fit just right works like a champ , good fast shipping

Works great and the price is right I will be buying 2 more sets as I finish my Builds

I run this behind a 4.75 inch barrel with a lightweight aluminum BCG found on this site with both 5.56 and .300 aac cycles and rows any ammo I pore through them. These guys always ship fast I usually receive my order in two days flat I am also in a connecting state. I have never had any issues with these guys or there sister site Davidson defense. I have placed several orders at least 10 and only had one issue (a missing buffer tube) I received an immediate response and apology a shipping and tracking number and a better buffer tube then I had ordered again within two days. I would recommend them to anyone and will be ordering more soon. Thank you again Team Delta and DD, Sincerely, John Petersen

I tried a JE double spring silent capture but it made the weapon jam repeatedly. This one works great. (same gun) sometimes these guns run better just the way they were designed. The more hot rod stuff you add to an Ar the more time you spend under the hood. grab this cost effective buffer spring and buffer because DTT ships fast. great bunch

haven't had a chance to use yet? But I am concerned about the 3oz. buffer being able to cycle a pistol correctly? I heard about issues with this? I am using this with a polymer lower and I'm curious how this whole build will work?
