OP continues to be the best place to shop for all things KAC! I was able to get a sand cutter carrier and mams 556 muzzle break kit. Great service, great prices and fast shipping is why I keep coming back to OP! Thank you!!

Colleen is at the top of my list of awesome people! Her customer service skills are unparalleled. She was very helpful and friendly, and assisted me in my purchase. I will be a continued supporter and customer of Operation Parts because of her!

Outstanding Service! The order was shipped out the next day and got to me in Commiefornia in 3 days! I am not in a hurry or was expecting it that fast. Great parts selection for all kinds of high end builds at very reasonable prices. Wish they had the Tan PRI upper and Lower, but I’ll grab that from PRI. Will order the rest of the parts from Op Parts very soon (pri gas block sight, SPR PEQ top rail, ambi mag release, etc.) 🇺🇸

Operationparts is the place for weapons parts, accessories, and gear. We as a unit and personally rely on them, their products and service and they never disappoint.

I recently purchased a SR15 upper after waiting for a long time and the transaction was super easy and shipping was incredibly fast. Will definitely be doing business again with operation parts.

OpParts has a great selection of hard to find parts and is my go to for odds and ends. The company doesn’t let orders sit in the que for 3-4 days before picking and shipping, like others do… A++. As for the swivel stud, I was hoping to convert a QD sling mount to a standard swivel sling mount, but it didn’t work out… thanks “forum guy”, HA! I’ll continue to use OpParts.

Pricing was nicely competitive and I received helpful tracking regarding my order.

Operationparts is my go to for parts. Communication is on point and delivery is quick.

Lightning fast shipping and product as described. New in the original box. Operation Parts is a great place to source hard to find gear. No questions on the authenticity when purchasing from these guys either. Thanks again!

Operation Parts has all the hard to find parts for cloners! KAC is always the best quality and you get what you pay for. Buy once, Cry once.

The Magpul handguard fit very nicely and it certainly helps with the looks of my A515. It gives me a better grip and easy handling. Great service from Operation Parts, and the shipping was second to none. Good folks to do business with.

These have been impossible to find but I got lucky. The quality of the tool is excellent and fit my upper perfectly. I would not hesitate to buy from Operation Parts again.
