This is a S&H roller sear. Very rare low friction sear. It resides in a four position burst trigger group set up for an MP5 ready to shoot. Absolutely runs flawlessly now. This item is on a form 4 in Kentucky. The shipping and transfer to your FFL is included in the price. $30,000. I will do 50/50 on this item and possibly interested in a trade on a M16 registered receiver? If you have any questions please contact me at rext269@aol.com or 859-361-9444.
Thank you for looking,
