Correct Weight To Cycle Your .45 Caliber AR Carbine Reliably

Whether building a new carbine or replacing worn parts, the Angstadt Arms .45 ACP AR-15 Buffer Kit contains the correct weight/size buffer and spring to ensure your .45 ACP AR-15 cycles reliably. A standard rifle or carbine buffer is not going to do the job, so Angstadt Arms came up with a .45 ACP AR-15 Buffer Kit that includes:

• Extended length, correct weight (8.4 oz.) buffer
• Carbine buffer spring

The Angstadt Arms .45 ACP AR-15 Buffer Kit is compatible with all .45 ACP AR-15s, and DOES NOT require the use of a buffer spacer.
