Ordered an upper and a couple other parts for a build. Didn't know what to expect honestly but I was incredibly happy with my purchase after I received everything. I liked that you could choose different upgraded and accessories to make it your own unique upper. Shipping was fast and easy got my order in less than a week, even being half way across the country.

Handguard Length QD Suppressor Problem
December 20, 2021
:
from Round Rock, TX United States
Quality of this assembly is great. But the major issue is that the length of the handguard (9.87") covers access to the lug nut of the muzzle brake. The pictures appear to show that the muzzle brake can be attached/removed without removing the handguard but that is not true. This makes this assembly incompatible with most suppressors unless you replace the handguard. Wish I knew this before purchasing. IMO the handguard length should be 9" standard to allow ease of muzzle brake and suppressor attachments. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Trevor, The 10.5" barrel installed on a 9.87" rail leaves room to insert a 3/4" wrench to remove the muzzle device without having to remove the rial. The handguard length is clearly mentioned throughout the listing. We do not make a 9" rail that you mentioned. We left you a message to discuss but have not received a call back yet. I don’t know what suppressor mount your using or how it attaches. You can try using a jam nut on the threads to lock down the can or purchase 1†barrel extension to install your can. Please give us a call if you would like to discuss further. Thank you for your feedback and your business!
