XH Carbine Buffer (8.5 oz) w/.308 Rifle Buffer Spring - $140
If you have an extended (7-5/8" deep) receiver extension on your .308 AR I recommend an XH carbine buffer and a .308 rifle buffer spring.
This includes VLTOR A5 tubes and the Magpul UBR Gen2 stock. Many .308 rifles come from the factory in this configuration - LMT, S&W, LaRue, POF, etc.
If you have any doubt please measure your current buffer and check the inside depth of your buffer tube. If your buffer is 3-1/4" long and your tube is 7-5/8" deep this is the best buffer/spring combo for your gun.
DO NOT USE an XH Carbine Buffer in any gun with a standard AR-15 carbine buffer tube! Damage/injury/mayhem will result.
Email us before ordering if you have any questions.
