JHP45

Crimson Trace CMR-206. High powered green laser for most daylight shooting and can be mounted on the top rail in front of most optics without obstructing the sight picture. I like that model because it's small and light. The Streamlight TLR-8 is a pretty good unit as well if you want a light/laser combo but will require an M-LOK Section. Looks too bulky to me on the charger but it was functional.

Gear Head Works Tailhook Mod 1 or Mod 1C if you like solid. If you need adjustable, Tailhook Mod 2.

I get 12 in the 30 and 4 in the 10. So far so good feeding wise with both but, truth be told, I usually run the 10 round mag body due to cost per round. I haven't had a problem with the 30 round body but also haven't done high volume testing with it either. The 10 round body is GTG in my 450 and has functioned 100% so far.

I've got an Aero/BCA build in 450 Bushmaster that was made for the exact purpose of I don't need it but it's a fun range piece. BCA ran a special on the uppers last year and it was more of an impulse buy. I got the 18" and run an A2 stock with a rifle buffer. I ended up loving it and all my range buddies like shooting it when I take it out. It vaporizes 2 liter bottles. Had good luck with 225 gr FTX over H110. Got data from the Hodgdon website. Mine has been 100% with unmodified Lancer magazines both the 10 round (223) and 30 round mag (300 BLK) bodies. Your mileage may vary but I've had good experiences with those. Recoil feels about like shooting slugs out of a pump action to me. Blast however is much greater. The thing has some bass to it.
