Excellent product, lightening fast shipping!
FCU with manual safety
Great work on adapting the FCU for a manual safety. Done at a reasonable price, similar to buying an FCU and adding the safety yourself, and delivered timely. Very satisfied with purchase.
Nicely done! It was definitely worth the wait. I have got to believe you will be getting more business re these conversions.
Love the skeleton black trigger
P320 FCU Stainless
I purchased the stainless/black FCU to better match the parts I am using and couldn’t be happier with the parts quality and overall purchase experience. The trigger is excellent and was shipped out very fast. Highly recommended for those people looking for another color than TiN. Great company to do business with!
Sig P320 FCU
Thank you for the fast service and product . I would absolutely do business with you all again
Great product, works perfectly
Order or pick up from AB Prototype! The owner is a super nice guy and laid back, he got the order shipped to an FFL the day I ordered it. Not much to say about the product, its a standard FCU that drops into a p320 module.
Product exactly as described!! Extremely fast shipping!! Will look forward to being a future customer of AB Prototype!!
2nd FCU and Wilson Combat frame purchase. Best products for any SIG pistol build
