Elevate Your AR-15 with Strike Industries’ Enhanced Castle Nut and End Plate

The Strike Industries Enhanced Castle Nut and Extended End Plate combo represent a step above the generic parts kit offerings. Designed to elevate both the form and function of your AR-15, this innovative upgrade delivers increased support and enhanced ergonomics.

The extended castle nut matches the length of the end plate, providing a more secure threading engagement with your receiver extension. This improves overall aesthetics and structural integrity. The extended end plate, in turn, features a centrally located Quick Detach sling swivel mount, positioning it away from the webbing of your primary hand.

This thoughtful design allows for seamless weapon manipulations in tight spaces and under stress, without the risk of a painful hand pinch common with standard flat QD end plates. While the first collapsed stock position may be lost, the improved ergonomics and control are well worth the trade-off.

Do not exceed 35 ft-lbs for castle nut.

How to return a defective item:

BEFORE returning any products, please visit the CONTACT US section to complete and submit the “Return for Refund/Exchange” form to receive an RMA (Return Merchandise Authorization) containing your name, shipping address, phone number, email, and reason for the return (including, if applicable, information about the firearm, ammo, and usage environment for defective returns). Please include a copy of the receipt if possible as well.
Once the RMA form has been processed, Strike Industries will provide a return shipping label for the refund or exchange of the product, including the shipping charges for non-expedited traceable shipping methods.
Wrap the item with sufficient padding and place it in an appropriate box or bubble mailer for shipping.
Ship out the package along with placing a printout of the RMA form we provided inside the box.
All processed and approved refunds will be applied to the credit card used during the original purchase. You should allow one to two billing cycles for the refund to appear on your statement.
Arrangements for a defective exchange or return must be made within one year of the warranty period, starting from the date the order is received. RMA numbers are valid for 14 days from the issue date. All packages received without an RMA number will be refunded, however, an automatic 20% handling fee ($2 minimum) will apply.
If the product was purchased from a 3rd party, Strike Industries provides no refund but only an exchange option.
