St-t2 heavy buffer too long to accommodate bcg - not carbine length for a .308 ar10 - Spikes Tactical Carbine Buffer Assembly Kit

I purchased the Spikes Tactical Carbine Buffer Tube Assembly .308 and paired it with a Spikes Tactical AR10 .308 BCG. However the ST-T2 Heavy Buffer is too long to allow for the BCG to fully retract into the tube causing feed issues. If you order this assembly with the intent for using it in an AR10 build you must purchase an AR10 carbine buffer separately because this set does not come with one. The buffer tube and spring are fine but the item description is misleading and does not stasify the product description. Loses 3 stars for the buffer and rated 2 Stars for the tube and the spring being adequate.
