My AR 300 pistol is failing to extract and and reload will this fix my problem Expert Answer

There is no way I can confirm that by using this kit you will be able to fix your problem. Your malfunctions could be stemming from just about anything. They could be caused by the bolt carrier group, magazine, gas system, buffer system, ammo, extractor/ejector on the bolt or something else. I would highly recommend reaching out to a local gunsmith to have them trouble shoot your AR or you can try to email us at techsales@opticsplanet.com, but you will need to provide ALL specifics regarding your firearm including

Buffer tube, weight and spring information

by Armando R., Gear Expert, February 14, 2020

It depends on a few things like barrel length, but I would recommend an H3 for the heavy calibers.

Purchased for a 1st build of .300 blackout. Fits and functions as advertised. Works well and cycles 225 grain sub-sonic without any concerns. Would consider again for builds in the future. No concerns.

You get what you pay for. by DW, Verified Owner, February 2, 2021
Unlike many of the generic buffer tube kits, this kit from Aero has always been in spec and always has a good finish. Some of the no name cheaper kits you can find online play loose with tolerances. I’ve not had one of these kits yet not work as it s...
