Frequently Asked Questions
Can I use a standard carbine buffer and spring with the BCM MK2 Receiver Extension?
No — the BCM MK2 Receiver Extension is specifically engineered to work exclusively with the BCM MK2 proprietary buffer and BCM MK2 action spring. Standard carbine or rifle buffers and springs are not compatible and will not function correctly with this system. Be sure to purchase the matching BCM MK2 buffer and spring when building or upgrading your rifle.
Will any Mil-Spec carbine stock fit the BCM MK2 Receiver Extension?
Yes — because the BCM MK2 Receiver Extension is manufactured to Mil-Spec outer dimensions, it is compatible with the vast majority of Mil-Spec rated carbine stocks on the market. Keep in mind that Mil-Spec tubes have a slightly smaller diameter than commercial-spec tubes, so make sure your stock is rated for Mil-Spec buffer tubes before purchasing.
How does the BCM MK2 system help reduce felt recoil compared to a standard buffer tube setup?
The BCM MK2 system — comprising the MK2 Receiver Extension, proprietary buffer, and action spring — is engineered as an integrated recoil management solution. The MK2 buffer's unique weight and design work in conjunction with the specialized spring to slow and smooth the bolt carrier group's rearward travel, distributing recoil impulse over a slightly longer cycle. The result is a noticeably softer-shooting AR platform, especially during sustained or rapid fire.
