I've wanted to put this rifle together for awhile now. So no time like the present. I'm trying to take the best of A1 and A2 put in one rifle. A solid buttstock and triangle handguard a must but the upper will have the brass deflector on it. I'm staying with the 18" barrel instead of 20" with the carry handle sight and front sight gas block going on it. Any thoughts I should be aware of or not forget feel free to share your opinion.
