E, member, from MI, United States, asked on November 11, 2021

Will this kit work for a .40 S&W ar?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on March 15, 2022

The Luth-AR 9mm Carbine Buffer Assembly would work but you may experience feeding/ejection reliability issues. Buffer weight for the AR 40 is going to be a bit lighter than that range (5.4-7.4 oz for AR9) due to the larger caliber having more pressure behind the round when fired. I would suggest buying a heavy tungsten buffer weighted at 4.3 oz paired with a pistol/carbine buffer spring. Email us at Techsales@opticsplanet.com if you have any further questions.
