Question: What size battery does it use?
Document: I was going to use this to practice in between going to the range. It is overpriced and the electronic target that came with it was questionable.
This is a well made, easy to use product that works. Laser dot is easy to see and the target products from LaserLyte work well too.
Save on ammunition use, fuel and vehicle use to range. Time optimization for practice and etc. No  waiting time for firing position.
Great Trainer, precise and accurate, lets you practice indoors without wasting ammo, nice laser, easy to use, easy to handle.
Using with recruits at the LE Academy. Excellent training tool allowing students to use own weapon during dry fire and giving instant feedback when used with the laserlyte target
Great price, very well made, and a excellent choice to save on ammo. You will need the associated training target to use with this laser. It works great to get you on target without emptying your wallet on ammo. I recommend this item to all .223 shooters.
I bought this and a 308 sleeve to use w/my silhouette rifle for dryfire practice. I had a smidgen of difficulty in inserting the 223 into the larger sleeve. I emailed laserlyte and was advised to place a smidgen of vaseline on the 223 cartridge. I did and the 223 slide all the way into the 308 sleeve. Works perfectly.
Bought this cartridge a couple months ago but wasn't able to use it till last week due to personal reasons. I really wish I had now because I would've returned it for a refund immediately! I have bought other products from laserlyte and so far are working pretty well. I have the LT-Pro for my pistols which is an adjustable laser and the thing is fantastic. It worked so good that I went ahead and bought the TLB-1 Laser target. The combination is great for training in the house.
When I initially received this item, it would only turn on if the back cap were unscrewed 1/3 of the way. A call to the toll-free Laserlyte customer service and three days later a free new back cap arrived at my house-same problem. Another call and 5 days later, they sent me a brand new unit. This one works flawlessly. No problems or complaints. It's easy to get good training and have a good time at it.
Well made. The rubber snap cap triggers the laser with each firing of the firing pin. I can not say how many firings the rubber snap cap will hold up to. But it hasn't worn down yet. I've used it about a month, right now.
